Problem with ESP32 #39

Closed zpowellman closed 6 years ago

zpowellman commented 6 years ago

ampy works well using wemos d1 mini, but has some problems with the ESP_Core_Board_V2 If I issue "ampy ls" command, the files in the directory appear. Issuing same command again, ampy hangs.

"ampy put file.py" sends file OK, but ampy never returns. Tried on 2 different modules.

sorry my fault, if I flash microPython firmware on the device ampy works... :-)

ampyesp32.txt esp32putty Here's my experience. jpg was taken after programming and reset. puTTY was then closed and ampy command issued. Board is ESP core_board_V2. Three boards operate pretty much the same. Thanks for looking Best Regards, Dan Powell
