Flash Errors #458

Getting this error every time when I try to flash. I connected to ESP32, flash is working fine only after 3-5 retries, never succeed on first attempt. Using the ESP32 USB connecting, running on Mac machine, anyone give what is wrong, how to succeed flash on first attempt.

Have you tried with another ESP32 module? It seems that you experiencing USB connection issue.

gopalakrishnan-subramani commented 5 years ago

I found that using this command 

 mos build --arch esp32 && mos flash

fails while uploading firmware.

But when I do them separately , flash is working fine. 

mos build --arch esp32

 mos flash

for me when i closed serial terminal, at the time only file loading successfully : )

After build connect board with host machine(Don't open serial console). Now you run $mos flash After flash completed you open serial console through putty or minicom

; )
