older esp32 pre-build images / is repl broken

Post by muth02446 » Sun Nov 12, 2017 2:43 pm

I am just getting started with micropython and esp32.

I tried using the esp32-20171112-v1.9.2-443-g236297f4.bin image from
http://micropython.org/download#esp32

But I do not get the repl prompt.
(My system is linux and I use minicom -D /dev/ttyUSB1 -b 115200)

Only after pressing the "en" button on the board does it appear.
However, it does not accept any keyboard input.

I would like to check with older images before filing a bug report.
Is there an archive for those somewhere?

I can find no problem with this build. I've connected with rshell and miniterm (115200, /dev/ttyUSB0) without issue. Check that you used the right esptool invocation as per http://micropython.org/download#esp32.

Problem solved: Hardware Control Flow was enabled and needed to be turned off.

For minicom the settings are hidden in
Menu::cOnfigure Minicom::Serial port setup
