I am trying use the stm32wb15cc to run an application on CPU1, but with no application in CPU. I don't need the RF side at all and want to hold CPU2 in reset and allow CPU1 to access all the Flash and Ram.However this does not seem possible as Option...

Hi Remi,I never got around to loading any of the RF stacks. I found this info about 'Safeboot' and tried both the FUS "FW Delete" and then tried to force the safeboot by writing the value 0x00008000 at the address 0x5800040C. After I rebooted, the SR...

Hi Remi,That was my understanding as well and the reason behind this post requesting FW. My backup plan was to try the different wireless stacks in the hope that each one only sets the protected area to only the size it requires, but I suspect they w...

Hi Remi,I commented out the line that enables CPU2 and used the debugger to confirm that the C2BOOT bit was not set. I used the CubeProgrammer to do a full chip erase. I then filled SRAM1 with 0xCAFE and confirmed that I was able to read and write to...

Hi Remi,Ok, I haven't explicitly loaded any wireless stacks, but my option bytes are already set. I am using the Nucleo-64 devkit for the STM32WB15, so this was probably already done before I even fired it up. Once we get our first revision of actual...

Hi Remi,Thanks for the reply, I will give it a go. I doubt it will work though, as the the RAM is locked by the flash option bytes. The documentation states that this prevents CPU1 from accessing the RAM whether or not CPU2 is booted or held in reset...
