Posted on January 08, 2018 at 16:10hello everybody,we use the SPC56EL70 discovery board with Spc5 studio as IDE and UDE STK - 4.8 as Debugger.Today we got the following failure message - please see the following picture.The only thing we changed was the additional usage of the A/D-port E12. After downloading the extended code we got the above failure message. Now we can�t flash the SPC with another source code.Please let us know how we can put the SPC back into operation. Thanks in advance. #processor-in-unknown-state

Posted on December 04, 2017 at 15:10Hello,I'm working with SPC570S-DISP discovery kit and SPC5Studio v5.6, and I'm trying to use EEPROM emulation in order to save some data for my application.I'm not using the flash drivers downloadable from ST site, so I'm trying to write my own code following the indications in RM0349 reference manual.What I try to do is:1) erase only the 4 8KB sectors placed in high memory (used for data memory)2) write 0xAA55AA55 at the start of data memory (0x00800000)The erase operation seems to be completed successfully (after operation, PEG bit in MCR register equals to 1), but write operation doesn't work (PEG = 0).Here is my code:#define FLASH_TEST_ADDR_0 ( uint32_t *) (0x00800000UL)uint32_t temp;uint32_t status_erase;uint32_t status_write;uint32_t *address;// eraseFLASH_0.LOCK1.R =

Posted on December 18, 2017 at 04:05Hi, I'm currently using a SPC560B64L7 and I wish to go into bootloader via FlexCAN without connecting pin PA[8] and PA[9], is this possible to do so? Best if I could do all this in my application code.

Posted on December 12, 2017 at 02:47Hi,I am using the sample application SPC570Sxx_RLA FreeRTOS SERIAL Test Application for Discovery and my hardware is the SPC570S-DISP board.I found that if i enable the 'Use software timers' in the SPC5 FreeRTOS component RLA, then generate and build the code, and program the board, debug through it, it suppose to stay in the 'vTaskStartScheduler();', but it doen't. It will step through it and fail the sample application. I wonder what is the cause for the failure? According to FreeRTOS documentation, if it run out of heap or other problem, it will step out of the vTaskStartScheduler().Did i do something wrong or the software timer is not supported?BTW, i noticed the Timer task stack depth is 2048, is that too much? I sort of noticed that during my experiment of my application, if i asked for 1000 stack depth for my task, the application will fail. But for the timer task stack depth, the ran

Posted on December 13, 2017 at 10:59Hello, if i wanted to program the MCU using SPC5 Connect via CAN, what kind of connection did I need to make between SPC5 Connect and the MCU? The MCU I currently using is SPC560B64L7.

Posted on December 12, 2017 at 02:55Hi,I am using sample application for serial operation on SPC570S-DISP, from serial_lld.c, it looks like SD1 is mapped to LINFLEX0 and SD2 is mapped to LINFLEX1. I have no problem read/write SD1, however i need at least 2 serial port, one for console and one for API. But when i add a line of code 'sd_lld_start (&SD2, NULL); ' after the original 'sd_lld_start(&SD1, NULL);', the application stops working. Debug showing it is stuck in the first xTaskCreate (...) function call i had. If i comment out the sd_lld_start for SD2, then the xTaskCreate function call can complete and application works. I wonder what i have missed.I have set the SPC570Sxx Low Level Drivers Component RLA/LINFlex Settings/LINFLEX1 to Serial (default was None). I don't know if there is any other place i need to change.Best Regards,Job#serial

Posted on November 30, 2017 at 02:49Hi,I need to use UART to send data from the SPC570S-DISP to a different board, looking at the UM2025 User Manual for the SPC570S-DISP: Discovery + Evaluation Board, section 2.9 LINFlex and UART, it says the LINFlex supports LIN Master mode, LIN slave mode and UART mode, but not much detail information there.So, what are the PINs i can use for the UART? I expect to find 3 PINs for TX/RX/GND, but for TX alone, there are TX, TXD, K TXD, LIN_TXD. Also is there any jumper to configure for the UART mode?Besides the UM2025, is there any other document that offer more detailed information about the SPC570S-DISP board? Sorry for being new to the board and lack some of the basic knowledge.Best Regards,Job#uart #spc570s-disp

Posted on December 04, 2017 at 14:33Hi,I'm trying to measure performance events with the integrated performance monitor but sadly I'm not able to make the performance counters run. I tried the follwoing to enable:# freeze all global counterse_lis       %r3, 0x8000e_or2i      %r3, 0x0000mtpmr       400, %r3 #set up pipeline stall event in counter 0e_lis       %r3, 0x27e_or2i      %r3, 0x0000 #event 39mtpmr       144, %r3 # un-freeze all global counterse_lis       %r3, 0x0e_or2i      %r3, 0x0mtpmr       400, %r3 But counter 0 (PMC0) does not increment. What am I missing?

Posted on November 23, 2017 at 00:43Hi,I have the SPC570S-DISP Evalution board which connect to my Windows 7 deskstop. Following the instructions from the ''PLS Debugger Installation driver on SPC560X Discovery board'' comes in the SPC5Studio software, installed FTDI driver, and 2 COM ports appears, using Putty connect to these 2 ports with 38400 bps, it gets nothing from the terminal.Is this expected or something wrong? The board is out of box without being reprogrammed. My board is SPC570S, but the instruction i could find is for SPC560X (wish i could find SPC570X documentation).Using import wizard imported the SPC570SXX_RLA SERIAL Test Application for discovery, i generated application and built, following the instruction from https://community.st.com/communi

Posted on November 10, 2017 at 08:56Hi,I want to use CTU in SPC56EC74 to trigger ADC conversions upon events generated by EMIOS Unified Channels running in OPWM mode. The ADC and EMIOS are configured and appear working, however CTU does not seem operational.As far as I understand the CTU has to be enabled by setting appropriate bit in ME_PCTL57. Quoting the xpc56ec.h:/* Note on PCTL registers: There are only some PCTL implemented in */ /* Bolero 3M. In order to make the PCTL easily addressable, these */ /* are defined as an array (ie ME.PCTL[x].R). This means you have */ /* to be careful when addressing these registers in order not to */ /* access a PCTL that is not implemented. Following are available: */ /* 104, 92, 91, 73, 72, 69, 68, 60, 57, 44, 33, 32, 24, 23, 21-16, 13-4*/union { /* Peripheral Control 0..143 (+
