I'm attempting to bring up a project on a Nucleo-H755 board using only the CM4 core (the CM7's boot is disabled). I have proved out that the ADC works as expected with polling and interrupts, but I can't get DMAs to function.I found and reviewed the ...

I'm attempting to set up a CI pipeline to build firmware built in STM32CubeIDE, but I've not been able to get STM32CubeIDE installed via Dockerfile without manual intervention. Is there a silent install or a way to pre-accept the license agreements s...

I'm attempting to use the serial bootloader to load a secure firmware image to an STM32L5 using STM32CubeProgrammer. I can successfully connect to the board in bootloader mode and perform a full-chip erase, but attempting to download the image (eithe...

STM32L5 - User Option Byte Access · 2021-09-30

The STM32L5 reference manual states that there are "4 Kbytes of option bytes for user configuration" accessible via the Flash register interface (section 6.3.1), but no further details are provided on how to access that space for user data storage.I ...

I'm attempting to switch to single-bank flash mode on an STM32L562ZET6Q (512k Flash), but so far I've been unable to get the Flash OPTR to operate as the reference manual claims.I used the normal process for modifying the OPTR: HAL_FLASH_Unloc...

A coworker helped me suss out the missing setting: The "Conversion Data Management Mode" setting needs to be in one of the DMA modes - in this case, DMA One Shot Mode. This properly enables the triggers the interrupts.

Based on looking through https://github.com/xanderhendriks/docker-stm32cubeide/blob/master/Dockerfile, it appears that adding `ENV LICENSE_ALREADY_ACCEPTED=1` to the dockerfile is enough to enable silent installation.

Understood, thank you!

Ah ha! (Sorry, I keep responding then happening upon a solution) I had changed my flash security settings when trying to change the DBANK bit, and it appears that I set all of the flash to non-secure, and therefore my secure code couldn't access flas...

Got it, thank you! I found an ST-Link and was able to change the option bits, but I'm still unable to write to flash, sadly.
