Hi, did you ever find a solution to this? I have the exact same problem (STM32L4).If the computer closes the VCP, when it re-opens, it receives the last packet that the STM32 tried to previously transmit. I want to know how to clear the USB TX buffer...
If your RDP is FF and seems like it's dead and can't remove RDP or change user option bytes, try check this thread:https://community.st.com/t5/stm32-mcus-security/stm32wle5-write-locked-not-in-read-after-passing-rdp-from-level/td-p/157014Try set RDP ...
Thanks for getting back to me. I know I replied on the other thread, but I'll document it here too in case others aren't reading the other thread. I'm enabling the clock protection, but I think something else is going on that's APB3/SPI bus related b...
Ok thanks for getting back to me, sounds like there's no way to fix it after it has gone bad. What's strange is that in the debugger, the SUBGHZ SPI registers all show up as 0 and never change when writing to them, and they always read back as 0. Wri...
DWalk.3, the RM states that SUBGHZ_SMPSC0R reserved bits must be kept at reset value, so your code in function RBI_IsDCDC(void) should be something like this:#if IS_DCDC_SUPPORTED == 1uint8_t register_read = 0;
register_read = SUBGRF_ReadRegister(SUB...
