Automotive MCUs

Hello,We are developing demo on Chorus10M using our EB's BSW stack with MCAL from ST.We are confused about how FIFO/filtering/mailbox/buffer is working on this chip.In user manual, we found statement like this: FIFOs will be assigned to CanHardwareObjects following the order of the receive objects created, i.e. FIFO0 assigned to the first receive object with elements count greater than 1, FIFO1 assigned to the second receive object with elements count greater than 1. So it means one can controller configured in configuration tool can have up to two CanHardWareObejects with element counter greater than 1.We tried and it is like this.But we also found that there is a FIFO Table to configure which can be configured up to 128 items. We do not know how these tables are working together with CanHardwareObjects.Could you help clarify to us?and, we also find statement in Chorus_10M_RM_rev1.pdf like this:Rx Handler: Controls the transfer of received messages from the CAN core to theextern

Is not clear for me How to integrate UDE PLS debugging in spc5 studio (eclipse).

It was asked by someone else before, but there was no answer, so I ask again.Where is the source code for TN1233?​Below link is a TN1233.​https://www.st.com/content/ccc/resource/technical/document/technical_note/group0/64/dd/1f/5c/49/a5/4b/58/DM00272195/files/DM00272195.pdf/jcr:content/translations/en.DM00272195.pdf​

How and where to download SPC58x MCAL?nThks!

I am able to set STOP mode in SPC560B50l3 successfully, but still the totalcurrent drawn is 6-7mA.According to datasheet the maximum current consumed in stop mode under 55 °C is 500 uA.Following is the code that i have added to set STOP mode:ME.STOP0.B.PDO=1;/* Pad power sequence driver disabled, but state */                     /* of the output is kept */   ME.STOP0.B.MVRON=0;   /* Main Voltage regulator is off */   ME.STOP0.B.DFLAON=1;  /* Data flash is in power-down mode */   ME.STOP0.B.CFLAON=1;/* Code flash is in power-down mode */   ME.STOP0.B.FXOSC0ON =0;/* Fast external crystal oscillator (4-16 MHz) off */   ME.STOP0.B.FMPLLON =0;/* FMPLL is off (default status during STOP0) */   ME.STOP0.B.SYSCLK=0xf; /* System clock disabled BEFORE RC switching off */ &nb

Hi DearsFirst (if its important):I want to program for 560b50 and it isn't in platform list. list started with 54. what should I do?Secondly :I configure "enable filters" in flexcan visual configuration from respective component and so generate ...but defined "SPC5_CAN_USE_FILTERS" have "False" value in all respective codes (cfg , header , lib).using spc560b CAN example , was the similar result and this defined , have "False"!I tried another family chip and everything was right. ("SPC5_CAN_USE_FILTERS" changed with visual configuration.)Do you think there is a problem?have I become sensitive?

We are facing issue with SPI slave communication for spc560C50L3 controller.The generated code for SPI slave from SPC5studio is not working. We have written a register level code to transmit 1 byte and read 1 byte for SPI slave. The observations for the above controller is detailed below.1. In fifo enabled mode the TxCNT increased when 4 bytes are pushed . We have pushed 'P' + Count++ as 4 bytes whereas count is zero initially.2. After master provides read for 10 bytes the data received is only 'P' character for all 10 bytes read. The MCU is not pushing next character instead the same character is transmitted. 3. The TXCNT remains 4 for each byte transfer. The TXNXTPTR does not increment at all. It remains 14. The bytes 'PQRS' pushed in fifo can be read from TXFR register but after pushing the 4 byte it does not update with new byte.5.The fifo does not get clear. It only transmits 1byte every time the master initaites a read request for 10 byte continuous read.6.At maste

When I look in the eMIOs Settings of the SPC560Bxx HAL Driver Component, I can only activate eMIOs group 0 (Channel 9..15) or Group1 (Channels 17..23) but as per my requirement i have to use Channel 7. But channels 0 to 7 can only be activated by ICU drivers. Is this right? Is there an other way to activate PWM on these channels?

Hi, I´m trying to implement the synchronous pulse width modulation for my Bachelor-Thesis. Therefore the frequency of the pulse width modulation is variable.I´m using the  SPC560P44Lx, SPC560P50Lx microcontroller family.So what I want to do is to adjust the Registers where the frequency is stored as the peak value of a counter.This is how my 3 Flex Pwm submodule-registers are initialized;for.....{ FLEXPWM_0.SUB[u08_counter].CTRL.R     = 0x0400U; FLEXPWM_0.SUB[u08_counter].CTRL2.R    = 0x2000U; FLEXPWM_0.SUB[u08_counter].DTCNT0.R   = 50U;    FLEXPWM_0.SUB[u08_counter].DTCNT1.R   = 50U;    FLEXPWM_0.SUB[u08_counter].INIT.R     = 0xF7A1; <------ This Value has to be adjusted every sampling period FLEXPWM_0.SUB[u08_counter].VAL[0].R   = 0x0019U; FLEXPWM_0.SUB[u08_counter].VAL[1].R   = 0x085

Dear Sir/Madam,I've PEMicro Multilink Universal debugger and I would like to configure debug functionality in SPC5Studio IDE.But, unfortunately, I couldn't able to see our device listed in Debug Configuration.Attaching Screenshot:Please let me know the device to choose to support SPC560B60L5 MCU core.Thanks for your support in advance.Best Regards,Prashanth Mohan

Hi all,Dear all ST's expert, somebody help me out, Thank you very much.An errors occurred while compiling, see below:assembler code:build result:​IDE: SPC5 Studio, version: 5.8.1Compiler: FreeGCC with VLE support or Hightec Pro

I am unable to generate pwm signal for PWMX pins. example hardware pin 26 (pwmx_0).

SPC58 docs mention HSM (Hardware Security Module) as additional core, but docs are very rare. How to run code on that core? Is there any docs how to deal with that processor?

..

I am working on SPC56xL Discovery+ kit(spc56el70l5) and i'm unable to generate pwm signal on PWMX pins. We are able to generate pwm signals on PWMA & PWMB pins respectively but not on PWMX pins.

Hi,  I checked UART register of Chorus 4M my environment.If I would like to set AUTOWU bit in LINCR1 register, is following sequence right?linflexlp->LINCR1.R = 1; /* enter INIT mode */linflexlp->LINCR1.R = 0x1001; /* set AUTOWU */linflexlp->LINCR1.R = 0x1000; /* exit INIT mode */When I wite '0' (0x00000000) to LINCR1 register to exit INIT mode like serial_lld.c in SPC5Studio (following), not only INIT bit but also other bits on LINCR1 register is clear. Is it right?/* Leaves the configuration mode.*/linflexlp->LINCR1.R = 0;If it is right, I think it is very important behavior.Best Regards,Tsutsumi

Dear all, I am working on a prototype with anti-tilting and park-brake functions that need to be complied with ISO26262. So far the ASIL is not determined yet, I want to start development and testing the firmware in a complete toolkit.However I am not sure which MCU to choose.For example, the SPC56 L line and SPC58 C line both provide ASIL and safety applications, and evaluation toolkit, though mentioned that SPC58 C key functions are securing on-board communication protocol.I have the same difficulty in selecting from other A/B/2B/G/P/etc.And how about the generic control STM32 MCU's, if I only want the mentioned two functions, it seems the STM32 MCU is qualified as well, is it correct?Thanks in advance for explaining with details.

Hello,I wan't flash program spc58ecx with spc5connect . I have learned the UM2108.pdf. But,i don't know what is CANC_TX CANC_RX EMIOS.4 EMIOS.9 UART_RX in spc58ec80e5 .Because ,too many uart on spc58ecx,and there isn't EMIOS.4. User manual is too confusion for me. !!!:pensive_face:

Is not clear how to change the linker file *.ld.I found the linker setting in SPC56ELxx Platform Component RLA but I don't know how to proceed. Is there a manual for all the linker option?if I understood well, I have to place all the option/command in the custom sections?Is it right?

Hi ,We are planning to use SPC560B40L3 Microcontroller .One of our requirement is to update the firmware of the micro controller over the air. Could you please let us know, how this can be achieved and whether the selected ST microcontroller support firmware update over air.Any Inputs will be helpful
