Automotive MCUs

I am new to stellar MCUs. Please share information on how to get the SDK for stellar P series or G series MCU. Which IDE is used? Is there any RTOS support especially FreeRTOS support?

Hi expert,I am using Stellar SR6 P7 line, e.g. SR6P7C8. According to the SDK there is RAM and System RAM reset operation when system boot,/* Initialize memories protected by ECC */ bl _raminit bl _sysraminitI want to get more information about clearing memories for ECC. Why these step are needed? Is this for DAN-0055942? Thanks.

Hi fellas,Whether STM's SPC5x AUTOSAR MCAL is free or licensed version. Also, its been told, it provides CDD and no AUTOSAR OS,for which FreeRTOS is used. Whether this FreeRTOS version for AUTOSAR is free/licensed?

Where can I download SPC5-UDEDEBGPLS JTAG debugging software! Not available on the official website! Can you give me a download?

I am looking for the BSDL Files for SPC58EE80E7QMHAY and SPC584B64E3ND00X parts, but couldn't find them in ST website. Please share the files.

I'm using a SPC570S microcontroller and I have 14 CAN IDs in my ID table. Only up to 7 IDs fire the CAN interrupt, however, if I move a lower ID to above 7 it works fine. I have set the number of RX mailboxes to 16 and TX mailboxes to 7

Hi I am working on SPC574S64 Controller, A20MHz Crystal is used in our boardI tried to configure it in the SPC5StudioI tried using one of the example code for the configuration where a 40MHz is used in the configuration and I tried to change to 20MHz, but could not succeedI tried modifying the dependent registers, but still nothing worked out.It is showing an error as below​I could see the ranges are as below for them​I tried changing the PLL0 Settings but nothing gave me the positive resultCould you kindly suggest settings for a 20MHz crystal​

Hi All,​I am working on SPC574S64 Controller​I am using the sample code from the SPC5 StudioPIT Time which toggles the port for 4ms, 2ms and 1ms​I have also observed one more issue with the crystal, I couldn't see the oscillation but could be my logic analyzer couldn't capture I guess​Today I am seeing a strange issue with my board.When the debugger is connected to the board, the code is running fineI could see the port toggling for the timer Interrupts ​but when the debugger is removed the code doesn't run and the port toggling is like random or garbage toggles which are inconsistent​​I have checked the crystal oscillator​ frequency but I only have a logic analyser which is of 24Ms/sec not sure if it is capable of capturingI checked with it but I couldn't see the oscillations are properKindly suggest, how to debug this ​​

I have two firmware saved into my Flash Memory at two different addresses (the former is a bootloader and the latter is my main application). After the micro is entered in Stanby Mode, I wish it would just load only my main application, skipping the bootloader. I tried to use some registers specified in the reference manual ( For example ME_CADDR0_ADDR or SSCM_PSA_SADR) but it doesn't seem to work.

I have a L9963E BMS development board, I have tried connecting to SPC5 UDESTK Debugger, the debugger is not getting connected (UDE STK Debugger) to the controller I have connected the power adapter and USB mini connector as well, I am using UDESTK Staterkit 2021 version from pls. The error indicates No Target Supply or JTAG Cable Connection or Target ConfigurationTargetConfiguration I have selected from the provided list Power to the board is proper I have connected the adapter and to rule out if it is taking power from USB of Serial cable, I have connected the serial cable i.e., the FTDI cable as wellToConfirm the power to the board is fine, I have ran the default firmware whichis shipped along with the board, it is getting connected to theL9963_evaluation_GUI program and serial communication is OK.  how can we connect the debugger, any settings needed in the development board to be done or any jumper settings need to be changed?AlsoIs there a facility to connect t

We want to work start on AUTOSAR domain. So, We are ordering Discovery Kit for SPC58NG Development board. We have some queries as below,This board is suitable for AUTOSAR Standards?Basic SIP is provided by ST or not along with development Board?Evolution Tool (SPC5 Studio) is free or not?Any other Tool or Kit need to purchase along with this?​

I am new to using this level of mircocontrollers but things were going well until now. I have written some code that can recieve CAN messages and then control a servo motor using PWM. However, I have flashed the board using "FLASH programming" button in the UDE STK software and now when I try to connect to my board through the UDE STK software I get this message Message from component 'PpcJtagTargIntf' : Can't connect target !   Message from component 'PpcJtagTargIntf' : No JTAG client found ! Please check: - target power supply - JTAG cable connection - target configurationFrom what I have read it seems that when I used the "FLASH programming" button the program changes the PFLASH configuration to be protected. It seems that I can set this back to unprotected while in supervisor mode. My question is how do I do this? How to be in supervisor mode? How do I then change the boards PFLASH configuration?

Hello I'm trying to run SPC582B60 can interface. I tried if CAN_TX pin is properly set, switching it by TEST register and it works. But to get rid of all hardware problems I set can port into the loop mode. Filters are set to accept everything. I send some data and I should receive them (no matter if baud rate is set to 500 or 134,56kbytes/s). Data are put to the can ram selected in appropriate registers but there is happening nothing - nothing changes but the timer register value: neither the fifo nor the interrupts. I think the problem may be in bit CCCR.ASM which is permanent set. I can't reset it with any method. Can register values, filter definitions in memory and message I'm trying to send visible on pictures. What I'm doing wrong? What to do to exit Restricted Operation Mode?

WE ARE USING SPC570S SERIES MICROCONTROLLER AND IDE TOOL-SPC5-STUDIO.WE ARE CHECKING THE OUTPUT ON CAN_H AND CAN_L PINS WITH MICROCHIP CAN BUS ANALYZER.BUT WE ARE UNABLE TO GETTING THE DATA.HERE I WAS DOING ANY THING WRONG CONFIGURATION ,COULD YOU PLEASE HELP ME..!!

Hi I've declare a 3 byte array uint8_t hex_str[3] and assign a value to convert Hex string to int using strtoul function the point is I set hex_str[2] = 0 but cannot.Here Is my code capture I do breakpoint at line rowIdx = (uint16_t)strtoul(hex_str, NULL, 16);but hex_str[2] is not 0 as I just assigned hex_str[0] and hex_str[1] is correct assigned by input array uRxBuf [12] and uRxBuf[13] That cause strtoul give out a wrong outputplease help correct me what I did wrongEdit 1:I try change type of hex_str to uint8_t, int8_t, char, unsigned char it give the same output

I figured out that R1 response format is different in the STM32 specification as the below But in the Physical Layer Simplified Specification, there is a definition of R1 Format.​Actually I expect that R1's response format is supposed to be the same in everywhere.But they appear different format in different specification.Can I get some explanation for this to understand?​​​​
