problem started when i attempted to upgrade, screen went black, foolishly did not save the old version.. now i can read the vna with stm32, it even appears to write the new firmware but still a black screen, how do i know if i am using the correct firmware for my vna? what are the correct steps to read and program with stm32? i must be missing something, any help would be appreciated.
thanks for any advice
