That's interesting, though it seems really tightly bound into the M5 ecosystem. Maybe it can be pulled apart into something more general purpose.

Thanks!

I see someone asked about the OTA process here https://esp32.com/viewtopic.php?f=13&t= ... ard#p57551 and I am also curious about using the SD Card to hold multiple firmware images which could be selected, say using an LCD menu with push buttons.

Some progress... I guess the onboard pullup through the R/2R ladder is actually not adequate. io_conf.mode = GPIO_MODE_INPUT; io_conf.pull_up_en = 1; io_conf.pull_down_en = 0; I added the last 2 lines to button_init() in button.c and no longer have the stuck buttons. Everything works as expected. Ke...

Here's another clue. (Note, I added IO36 to the list). If I hold down key 6, which is connected to IO5, and reboot, I get: I (1272) BUTTON: Registering button input: 5 I (1272) BUTTON: Registering button input: 13 I (1282) BUTTON: Registering button input: 18 I (1282) BUTTON: Registering button inpu...

OK here's where I am. I'm using the AiThinker A1S WiFi/BT/Audio board. The schematic is here: http://wiki.ai-thinker.com/_media/esp32/docs/esp32-audio-kit_v2.1-open_custom.pdf There are 6 buttons which route to IO5, IO13, IO18, IO19, IO23, IO36. They are pulled up via an R/2R ladder which eventually...

I am using the ESP32-A1S AIThinker audio development board. The switch buttons are pulled up through on board resistors, value not marked in the schematic, in what looks to me like an R/2R ladder arrangement? I've never seen that for button input but I guess this would let you input a binary value. ...

I found some articles talking about different ways to go about this, but it seems to me like it should be a basic function. I'm using ESP-IDF at the moment.

Thanks,

Putting the baud rate on the cmd line works, thanks!

I've tried setting different speeds in the menuconfig

Serial Flasher Config-> 'idf.py monitor' baud rate (921600 bps) --->

No matter what I set it to, when the program goes to flash the board, it still reports as 460800.

??

OK, that's another approach I might try. So, you don't have any problems flashing the board over USB using Ubuntu in Virtualbox? Looks like from the error I got it had some problem adjusting the baud rate. And to be clear, this error does not happen when doing the same thing in the Windows native ES...
