STM32L series first write to EEPROM fails

I have an STM32L073CZ that I'm having an occasional error with. I'm using the HAL libraries to program EEPROM and a number of our MCUs are seeing errors where they fail to write the first word. After that it'll start working correctly and everything ...

On the STM32H (not L) I need to use a 1-wire EPROM, and I try the generic driver calls generated by the IDE (HAL_SWPMI_Receive, HAL_SWPMI_Transmit, HAL_SWPMI_MspInit, etc.) and I see no bits going out on the scope, and the transmit times out.

I can "Transmit" but the TXE flag never clears and the transmit times out. It's unclear which parts of the bus are fully automated (reset, discovery, etc.) and how much of the CRC is handled, etc. I can see nothing on a scope, but if the chip gets in...

Resolved! STM32f030k6 CRC Config error

I want to use CRC on STM32f030k6, but as soon as I enable it, some errors appear and compilation fails.Even when I want to use EEPROM Emulation example for the above micro, again it fails to compile.What is wrong?STM32CubeIDE - Version: 1.10.1STM32Cu...

SBSFU - Start in different flash memory sector

Hi,I'm using a STM32F722RE and in my current application, I used sector 2 and 3 of the flash as a virtual EEPROM. The memory of the controller looks like this: So sector 4 should be enough for the SBSFU and I would like to set my application to secto...

Resolved! Setting up EEPROM emulator for STM32L

I'm trying to use EEPROM emulation API in a project. I have downloaded the expansion package. Based on AN4894 I need core and porting to be included in my project so I copied them under a new directory in Middleware and included the path. Then added ...
