Hello,Currently I'm playing around with the I3C peripheral and I try to implement a sort of "eeprom" interface on a I3C target where I have 10 slots which I want to be able to address separately.So on the controller side I have this function: int i3...

Hello,I'm trying to implement an I3C target device which sends inband interrupts when I push the blue Nucleo button.But I also want it to be ready to receive data via a private message.To do this I call `HAL_I3C_Tgt_Receive_IT` after receiving a dyna...

Hi All,Today I received two NUCLEO-H503RB boards, but when trying to get the ADC calibration values the processor HardFaults. According to the datasheet it's the correct address: Also when trying to access it with the debugger it failsAlso the temper...

Currently I write locked the first few sectors of my STM32U575xx. However I would also like the unlock the write protection. Since both J-Link and the ST-Link cannot do this I thought about writing a small application and run it from RAM to reset the...

I'm working on a project where we are using the new STM32U575xx series. Now I created a bootloader and wanted to write protect the bootloader section. However I'm not able to disable the write protection using the ST-Link v3 and STM32CubeProgrammer.I...

Yeah the example works perfectly, the problem is that if you are a target you have a receive or transmit action active when you are in "idle" because you want to be accessible by the controller.You must abort this action before being able to send an ...

Thanks to @CMYL and @SofLit I found it to be working with the following MPU configuration and ICACHE enabled. /* USER CODE BEGIN 0 */ void MPU_Config(void) { HAL_MPU_Disable(); // configure the MPU to prohibit access to after the .bss ...

After steps 1 to 3 you can reset the WRPStart and WRPEnd to there factory default to disable the write protection. There factory default is 0x7f for start and 0x00 for end.

Oke I got it working, I forgot to reset the actual write protection:/** This function checks if the lock bit is set and handles unlocking it */ static void disable_wrp_1(void) { FLASH_OBProgramInitTypeDef ob = {0}; ob.WRPArea = OB_WRPAREA_BANK1_AR...

However after removing the write protection using these steps I am still not allowed to program the previous locked pages. Any idea on how to fix this?
