Thanks for the refs to the docs dhylands, I very much appreciate your writing rshell it's been very useful! What I'd like to know particularly is whether there's a convention, however loose, for the content of 'board.py' files? For example, the Adafrult Blinka uses a board.py file, which makes me th...

Thanks, davef, for the quick reply! I'm sorry to say that I was interrupted while writing a question about board .py and when I returned to complete the post I'd just been working on boot.py... and thus made a typo in the subject and body :oops:. I've corrected that now and the subject and body both...

Edit: correct typo in subject and body, board.py is the file I'm enquiring about! Hi everyone, I connect with rshell to an ESP32 and rshell looks for via the function below which, because my code doesn't contain a file 'board.py' and thus always defaults to "pyboard". I can change that in a simple-...

Thanks, Roberthh, that helps. I believe I tried sd.deinit() while troubleshooting before posting but - as indicated in the documentation - it appeared to do nothing on the ESP32. I'll look into how/whether there are alternate methods for deinitialising the SPI device from MicroPython code. I'm glad ...

Raised on the MicroPython GitHub project as ESP32 machine.SDCard() Instantiation throws error on soft reboot: SPI bus already initialized; ESP_ERR_INVALID_STATE #8949

I'm not sure that the sck, miso, mosi, etc. options take machine.Pin() values. What works for us on MicroPython 1.14 (see my recent post ) is to just pass the logical GPIO numbers. In your configuration this would be: my_sd = SDCard(slot=3, sck=14, miso=12, mosi=13, cs=32) Our experience is that non...

Hello everyone in the MicroPython community! We're having trouble with microSD card access with MicroPython versions 1.16 through 1.19 on two different revisions of a single-board PCB based on the ESP32-WROVER-B (SPI RAM) with direct connections from the ESP32 pins to the pins of a MEM2075 microSD c...
