I am getting an error with the py_uploader tool on an FMU v5 board. If I update using QGroundControl and the .px4 file everything works but when I do a “make px4fmu-v5_default upload” it always fails at the verify step and it looks like the bootloader doesn’t send any data back. Any one else seen this problem?
Solved. I had to increase the serial timeout to 1 second. I’m guessing the larger flash on v5 takes longer than the default 0.5 seconds to generate the CRC and respond. The timeout in Q GroundControl is 5 seconds.
