I am writing a Flexray driver for SPC56. And I follow steps that mentioned in document. But there is not detail description in that document : SPC56XL70xx 32-bit MCU family built on the embedded Power Architecture® (st.com) . Like protocol initialization 1.c in flexray application information on page 903 : "configure the FR_PCR0,..., FR_PCR30 registers to set all protocol parameters" and there is no information that registers default values and which ones must be configured. Do anyone have detail flexray configuration document or anyone could help me?

Hello everyone,I'm struggling trying to compile an old project without having to regenerate the configuration files, this project was made under the ppc freegcc with vle support V4.9.2 ,I tried to compile using the last actual version(4.9.4) and I'm facing a lot of problems.From what I understood in order to correctly compile we need a PATH that include 3 locations :1-The Make.exe location2-gcc.exe location (Plugins/GCC-plugin-version/toolchain/bin)3-ld.exe location (Plugins/GCC-plugin-version/toolchain/powerpc-eabivle/bin)Thing with using that version is that we will need to update the crt0.s file otherwise we will have linking errors, (I don't know if updating other s file is necessary) Could someone please tell me how can I get the older version ? I'm just looking for that particular plugin<< com.st.tools.spc5.tools.gnu.gcc.ppcvle.win32_1.0.0.201611101103 >>Thank you for you help.

Could the BAF_BYPASS field in the BAF configuration DCF register by modified by the user.If yes, under which module can I find it? I'm unable to find this in Lauterbach debugger.If no, how can I skip the BAF section during the bootup? - My device has pre-programmed BAF region.Thanks!

Could you send us the datasheet of L9966, we want to know the difference of L9966 and L9966CB. Is L9966 EOL?

hi, I would like to know if it is possible to read mcu SPC56EL60L3 with usb / uart adapter with software SPC5 FLASHER?

I am working with a SPC582B60E1 64 pin Flat pack chip. I am trying to program GPIO11_INT24_PWM16_CAN4SYS1_RX_WKPU pin 53 as a PWM output. But I am not sure if it is even possible. I consulted the SPC5 LLD Drivers for RLA components document for PWM low level driver and in that section of the document has a diagram showing the physical and logical channels. I took a screen shot and attached it for reference. It shows that that of the eMIOSx channels, that channels 8, 16 and 24 do not have PWM Drivers. So does this mean it is not possible to set channels 8, 16 or 24 as a PWM channel? If they can be set to a PWM, could you include a code snippet to set it up? Thanks,Steve Lam

I am doing my bachelors degree and have a task to get two boards communicating using the CAN bus. I just got the boards and they pretty much said "have at it" without any prior knowledge. By now i know most of the really basic stuff about the CAN bus and SPC5Studio but I don't know where to start and what to read. The boards that I got are aek-mot-3p99081 (with the motor) and spc58ec-disp. I also downloaded all of the necessary stuff for the SPC5Studio such as AutoDevKit, MCTK etc. I underastand that i need two terminating resistors and then connect the boards?I am supposed to load the programs to the board and test them out seperately and then start testing the communication between them using the CAN bus. How can i do it and where to start? And might there be a really bored expert that can help a student out for some weird reason with a call or explanation. Thank you for reading :).

Good morning everyone,I'm facing some trouble compiling a project made by SPC5STUDIO 5.8.1 the project is configured by written makefile and rule.mk file.I tried with the last release (V6) and it's not working after importing the project (I did save after the configuration.xml was updated by the spc5studio ), I have compiling errors make:ex: *** No rule to make target 'LINIF.c', needed by '/obj/LINIF.o'. Stop.I guess there's some procedure to follow in order to upgrade the SPC5 studio configuration.xml file in order to make it work.I would like to try with the previous version of spc5Studio but I couldn't find a way to download it , could someone share a link for that version?Thank you.

 have used SPC560B54L5 controller. I am enabled UART over LIN but I don't how to configure UART interrupt and how to use IRQ_HANDLER(SPC5_LINFLEX5_RXI_HANDLER) function for receive and Transmit.

Hello, there may be mistake in ST library. In reference manual registers are like that.In the library SEMA4_RSTGT has two different addresses for read and write but those are in the same address.With this when I try to reset gate it goes to one of error handlers, if I comment out RSTGT_W I can reset gates without any problem.

how to use UARTto receive data on interrupt instead of using this api (sd_lld_read) as this works in blocking mode in while loop.Micro is SPC560P50L3.Is there is an example to use the Uart Rx on interrupt.As we use this method in Stm32.

Hi,I have configured 5 CAN Rx messages using Dedicated Rx buffers. In between running, I am losing CAN Rx message reception. DRX flag in the IR register is not being set once the problem occurs, thereby missing the Rx messages.I need a power cycle or software reset to come out of the situation.Please can somebody help me to solve this issue? Your help is much appreciated as this is an urgent issue to be fixed in our project.Best regards,Sreejith

Posted on February 28, 2018 at 08:40       My company is working exclusively with Linux, and we have interest in the SPC5 MCUs. But I couldn't find any toolchain for Linux. the SPC5-STUDIO is based on eclipse and claim to be an 'OpenSource Integrated Development Environment' so I was really expecting to find it on Linux, but the download page only provide a Windows binary. Is there any solution for Linux users ?   #spc5studio #linux

if you configure one CDTM.DTM right after one TOM and use it to generate TOM_OUT and TOM_OUT_N, what is the smallest dtz interval you have been able to achieve?if I set the DTM to be clocked with SYS_CLK (100MHz), still the dtz gap can't go anything smaller than a 5usec resolution (i.e. 0, 5usec, 10, ..). Are we sure about that (DTM clocked @100MHz)? By using another TOM channel and comparing edges (knowing how the DTM_OUT is generated from the original TOM edges), it looks as if the DTM is clocked at 200KHz only (but I may well be wrong on this)This is both odd and funny at the same time since the SPC5Studio GTM wizard configuration page computes and shows correct intervals out of DTM channel RELRISE and RELFALL register values the user fills in. Using an oscilloscope on TOM_OUT and TOM_OUT_N signals, I have concrete evidence of the phenomenon (5 usec min granularity)... Anyone faced this already?Thanks in advanceMo

Hello, I am using SPC58EC-Disp board. Core2 is already active and has timer interrupts. I need to set a timer interrupt in Core 0. I am trying use PIT0 and PIT0 configuration is done by Core2 so I think I only need to do PIT0 Channel settings. Two cores are using same vector table but different IVOR tables, I can set PIT0 Channel2 interrupt for Core2 from Core0, Core2 handles that interrupt very well. When I set same interrupt for Core0 from Core0 it goes to IVOR1. Let me explain this way. If I change first red area like 0x2000 | 4 to set interrupt for Core2, interrupt and Core0 work well or if I don't enable interrupt in second red area interrupt doesn't work but Core0 is working well. If I don't do these changes and let it be like in the picture(interrupt is enabled for Core0) it is going to IVOR1 handler always. https://community.st.com/s/feed/0D50X00009XkXkKSAV here Erwan suggests to look LR register. Its 0x00008000. What did I do wrong? And how can I fix it? Thanks in advance.

Please help to advise whether encounter this ​kind of issue as per below picture for reference as both part no. are still active in STM website which different in memory size.
