Hi Everyone,I have been using SPC563M64L7 MCU Discovery board and created simple application utilizing PIT  with two channels , which interrupts with 1Hz and 10Hz frequency.The following main.c code toggles LED1 for Channel1 with 1Hz frequency and LED2 for Channel2 with 10Hz frequency (by using callbacks of two channels) . While this works well (according to logic)  with Load in RAM (Boot Mode) it does not work with Execute from Flash (Boot Mode).Does anyone know any root cause of this ? What I should be investigating ?  Regards,Mirek 

Unfortunately we experienced some serious issues with the Teseo-LIV4F regarding custom configurations on the CDB-ID 201 register.While the issue with broken NMEA output seems resolved by disabling I2C (See other topic)https://community.st.com/t5/gnss-positioning/teseo-liv4f-broken-nmea/m-p/886937#M1324Another issue remains: Completely missing $GNGGA frame at 9600 baud, but only when the device has a fix.Steps to reproduce:Flash the latest firmware (4.6.8.5.11)Disable I2CDisable GSV, VTG, GST, GSASet Baudrate to 9600Save settings and restartCommands:$PSTMSETPAR,1263,0x1,2 $PSTMSETPAR,1201,0x8001C,2 $PSTMSETPAR,1102,0x5 $PSTMSAVEPAR $PSTMSRR Connect to the device using 9600 baud, above should output RMC, GGA and GBS frames. At first this works, but as soon as a fix is reached the GGA frame is omitted: (Optionally send another $PSTMSRR to catch initial situation where GGA is still present)$PSTMVER,FreeRTOS_V10.4.3_ARM*57 $PSTMVER,BINIMG_STA8041_4.6.8.5.11_ARM*34 $PSTMVER,SW

Evaluating the L9963E BCC chip for a BMS design, using the AEK_POW_BMSNOTX eval board together with AEK-MCU-C4MLIT1 (spc58ec) running the example BMS application as reference but seeing some odd results in the cell voltage readings.All readings are a bit low compared to actual cell voltage, but cell1 and cell14 are off by a fairly large amount.What could be causing this?cell1 & cell14 reading off by 0.5vcell2 to cell13 reading off by about 0.1vCell1 reading seems to improve if the HotPlug selection jumper is mounted. But not cell14.

The SR5E1E7 program written with a trimmed library, Makefile, and blank project file has locked up the chip. After a full chip erase, the demo program can be re-flashed successfully, but flashing my own written file immediately locks the chip again. It has been identified that the DCF address 0x1ff00100 cannot be modified. May I ask what the reason is?

I'm attempting to update the firmware for the LIV4 GNSS module, and everything seems to goes well until the CRC step, where it hangs for a few seconds then reports a failure. The module is no longer publishing any data, but when using the 'recovery' method for firmware updating, the module does communicate with Teseo_Suite, but it stops responding on the CRC step.  I'm using an FTDI and can see both RX and TX LEDs illuminate during the process,  but neither light up during the CRC step.  Any help with this would be greatly appreciated.Thanks in advance, -Jake

I have been attempting to get a GPS lock with the TESEO-LIV3F, and I am not able to.  I am fairly certain that it has to do with how I designed the signal chain from the chip antenna to the RF-IN pin on the LIV3.  I have ensured that it was outside with a clear view of the sky, I have sent the $PSTMCOLD, 6 command to it.  I have tried to initiate with this command; $PSTMINITGPS,3912.826,N,11939.993,W,1487,17,02,2026,21,11,30, but then later sent $PSTMRESTOREPAR to reset it.  I do not have teseo-studio seeing as I am on linux.  Any help will be appreciated.

Hello, I am designing a PCB atm with the STA8090WG and I am searching for a reference design/layout recommendation for this IC, including the caps to use and recommendations on the antenna matching. Does something like this exist? It would be really helpful for me.Thank you very much, Val

For JTAG I am using stellar link debugger, and I have to connect this debugger with microcontroller which is powered with other power supply, how to isolate or connect these connections, any digital isolator is suggested for this ?

I have not been able to find any documentation on how to use the StellarStudio tool. Does any publicly exist, or does this need to be supplied by an FAE? Thanks.

Hello community,I just wanted to know whether you know of a clock tree wizard for SPC58xE.I read in one post some years ago that there is no clock tree wizard for SPC58XE, but is there still none?Is there any possibility to visualize the clock connections? Kind regards Tkorn

I am working with the Teseo-LIV3F GNSS module, I would need to know whether the velocity field it produces, which is a module, is calculated over the x and y dimensions only or x,y and z Thanks for your help

Good morning!I've been working in a project whose purpose is communicate AEK-MCU-C1MLIT1 board and AEK-COM-ISOSPI1 through SPI/isoSPI protocols. At first, I've tried to apply the hardware configurations and script as mentioned in the user manual(UM3187) to exchange 512 bytes between two devices through isoSPI, however I don’t know how reliable the results in debug step are to assure this communication is working properly. Another detail that I've noticed is about disable pin, which stay always turned on, mainly when I select configuration as “micro” in  AEK-COM-ISOSPI1 Component RLA > Application Cofiguration. What should I do to enable AEK-COM-ISOSPI1 board?About the wire connections, I used as reference the board view within AutoDevKit Studio. I’d like to know if there is some connection that is missing, especially about the ISOm e ISOp signals, because the board view doesn’t show if I should to connect the USB port on the computer to debug step, for instance. 

Is there a way to turn the DC off on the RF_IN port on the LIV4 GPS module?  There must be an enable or disable feature available via firmware.  Thanks for reading.Scott

Hello, i am evaluating Teseo-ELE6A module and i would like to know if NavIC can be configured as a "standalone" constelation, without being combined with GPS,Galileo,etc....In the documentation it is mentioned:NavIC (IRNSS) The module is designed to receive and track the L5 (1575.42 MHz) signal provided by the indian NavIC (IRNSS) satellites system. The module can receive and process NavIC (IRNSS) concurrently with GPS, GLONASS, Galileo, BeiDou, and QZSS.But it is not clear if it can work without GPS, Galileo, .... Could someone tell me if this mode is supported and if there any statistics (time to fix, hdop, vdop, etc....) regarding its "efficiency"Thanks in advance for the help

Hi all,to evaluate LIV4F and MAX-M10S, I use Mikroe "GNSS 9" and "MAX" click boards with a passive antenna (Quectel YEGT001W1AM).While the MAX click board with the MAX-M10S gets a fix in less than one minute, the MAX 9 board with the LIV4F doesn't get a fix. Even when starting with an active antenna to get a fix and then switching to the passive antenna, the LIV4F stops operating. Sporadically, the GSV sentence shows then one or two weak (~20) signals while the MAX-M10S has >10 satellites with signals in the range 20..44.From my understanding of the data sheets, both the LIV4F and MAX-M10S should have similar performance without an external LNA, isn't it?Is there any known issue with the Mikroe GNSS 9 click board?Or a possible misconfiguration of the LIV4F I could fix? 

Hi,Could you please provide more details about the Stop Detection Algorithm referenced in CDB-ID 200? The documentation we have contains very limited information about this feature.Specifically, we would like to understand:- What is the purpose of the Stop Detection Algorithm?- How does it work?- What are the configurable parameters and their recommended values?Thank you in advance for your support.

Liv4F module.  Operating voltage range in the data sheet stated 3v-3.3vIn the Manual 1.8v-3.3v  what is true?  Can you fix the documents???

Hello — please help with the following questions about parameters:How should I correctly configure the TCXO frequency parameter $PSTMGETPAR,1245 (TCXO Frequency)?How should I correctly configure the CPU clock speed parameter $PSTMGETPAR,1130 (CPU clock speed)?To improve PPS accuracy, is it correct that the CPU clock speed should be set equal to the PPS Clock?What are the maximum supported values for the PPS Clock and for the CPU clock?

We would like to use the TESEO-VIC3D GNSS receiver as a replacement part without modifying the design.Could you please confirm or comment if the following hardware connections are acceptable for this module?Pin #1 (WakeUP): Pulled-up to VCCPin #4 (WHEELTICK): Not connected (floating)Pin #7 (Reserved): Connected to GNDPin #15 (FWD): Not connected (floating)Thank you very much for any help in advance.

Hi all,While implementation of CanTp, I am getting some errors regarding undefined reference which are shown in the snippet attached. I debugged completely but I am unable to find from where and for what these errors are coming.It would be more helpful if I get some support regarding this issue. Updating MediaThanks,Shiva Shankar.

I've been trying to get the Virtual_COM_Port app running on the combination of X-NUCLEO-LIV4A1A and NUCLEO-U575ZI-Q board and the best I can get is where the app will successfully output the first second's group of NMEA messages to the PC running a terminal emulator program and then it stops.  After it stops, the actual LIV4 module on daughtercard cotinues to run as you can see the RED LED blink pattern change.This happens in all three cases where I:Try running the pre-compiled build of Virtual_COM_PORT .bin file for the U575XI baord under the repository folder.Build the example project under STM32CubeMX, code generate it for STM32CubeIDE, build it and load it to the U575ZI board and run it (either in run or debug mode).NOTE: In this case, I do get one compile warning where I complains about a missing .c file in the Src folder (worked around this by finding it in a different folder, copying and build).Follow the steps in the GNSS1 FW getting started guide and manually setup the pr

I have been working with both the Teseo-LIV3F and Teseo-LIV4F GNSS Modules. The Liv3 software datasheet contains all of the information I needed to set up that module. The Teseo LIV4 software datasheet is much shorter and seems to be missing some of the content that is in the Liv3 datasheet. Some of the settings such as the FIX RATE, are documented in the LIV3 datasheet, and work the same on the LIV4. But some of the features such as the CPU statistics message, or setting the CPU FREQ, are documented in the LIV3 and work for the LIV3, but do not appear to work the same for the LIV4. I also noticed that the LIV4 has many fields marked as reserved, which the LIV3 has details for and options to enable. Are all of these reserved fields, functions that are not available on the LIV4? For example trying to turn on the  $PSTMCPU message on LIV4 does not work, but that field is also marked as reserved. I also wanted to ask about the constellation combos. We have been keeping it at the
