my plans to 2022 is to test on STM32L071, because we sell STM32+SX1276 modules and i want to test the LoRa!

To me the U5 seems to essentially be a re-spin of the L5 on a new technology node. However, the IP blocks have been updated considerably. I assume such subtle differences in the IP blocks have been the reason for the breakage problems you mentioned? I agree with you and will start a new stm32u5 arch. Thanks again Michael Am Do., 9.
