Posted on March 08, 2018 at 21:27 I just spent two harrowing days debugging random memory corruption in my application and the problem turned out to be overly aggressive cache invalidation. In sd_diskio.c this section of code (STM32Cube_FW_F7_...
Posted on March 27, 2018 at 13:31HelloIs it safe to connect board to two galvanic isolated units? Power selection jumper (CN3) set to USBHS, USB ST_LINK cable connected to Notebook1, USB HS cable connected to Notebook2. Both notebooks work on batter...
Posted on March 30, 2018 at 03:59I can see in the Application project for STM32H743I_EVAL LwIP>LwIP_HTTP_Server_Netconn_RTOS that the application is using a custom fsdata.c file. In the code elsewhere there is a define that directs the use of fsdat...
Posted on March 29, 2018 at 23:02I have my program something like this below.My question is under which condition (block 1) codes executed and (block 2) codes executed.1. At board power up, (block 2) executed. (for sure).2. If I erase the CPU, repro...

Posted on March 08, 2017 at 00:10Hi,I am using an STM32F103 connected to an I2C device. I can see that the device is responding to 2 ranges of addresses, one mapped to registers, one mapped to an EEPROM address space. I can communicate with the devi...
Posted on March 21, 2018 at 09:00I have tried to use SWV on DISCO-Board STM32F746 with Firmware V2J30M19. It does not work. But it works with Firmware V2J29M18.On Nucleo STM32F746 SWV work with both Firmware versions.Is this a common problem?
Posted on March 29, 2018 at 16:02Hello,for debugging our systems in production where the firmware is not yet flashed on the chip, we want to control attached peripheral devices only with SWD. So far we can switch GPIOs successfully with SWD. This gi...
