out of mpfshell, rshell and ampy only mpfshell continues working after putting main.py on a board

Ampy version: 1.0.7 Rshell version: 0.0.16 Mpfshell version: 0.8.1 Board: Wemos Lolin D32 System: Debian Buster I already have submitted the following issues to the `ampy` and `rshell` github repositories [1,2]. Since i'm not sure, whether it's really related to the software, i post a summary of the...

Re: Connecting to doit.am boards fails

Today i received a new development board: Goouuu-ESP32. Now almost everything works as expected. After flashing the newest Micropython firmware to the device my testcase yields: johannes:~/esp/Micropython % ./testcase.sh Failed connections: 0/100 However after Uploading boot.py and main.py with an i...

Re: Connecting to doit.am boards fails

I made further tests and I have discovered a special case: If there is an infinite loop (while True: ...) inside main.py and the script runs on the uC, rshell is not able to connect to the uC anylonger. Out of 100 tries there was not one successful attempt. Since i'm very new to the esp32 and i have...

Regarding the boards you've mentioned, I don't have any insights to offer. Sorry. My remarks related to a different board, which you apparently aren't using.

Good luck!
Thanks anyways!

Re: [STM32H743] How to flash

Thanks for your answer. It seems to be only available for Windows. Is there something similar for Linux? It's been a while since i played with stm32 boards but i remember that i needed a jtag device and openocd [1] to flash and debug the firmware, but it's been 5-6 years ago. Maybe there are other ...

Re: Connecting to doit.am boards fails

Not sure which doit board you have, but if it's the one that has the arduino uno form factor, it's notorious for not wanting to "do it". I have this board: http://www.smartarduino.com/view.php?id=95103 Its form factor is more like the one of the arduino nano. Maybe you have any references at hand t...

Re: Connecting to doit.am boards fails

Thanks for your reply Peter. I also tried it with rshell and the connection fail rate is about the same: approximately 50 failed connections out of 100. This connection issue makes the programming workflow really annoying and i wonder if i'm the only one experiencing it. I tried to check the power s...

Connecting to doit.am boards fails

I am pretty new to the MicroPython world and started experimenting with two doit.am boards [1,2]. I successfully erased the flash, flashed the MicroPython firmware and programmed the chip with mpfshell and rshell. Unfortunately establishing a connection with mpfshell and rshell is a very unreliable ...
