[SOLVED] WiPy 3.0 firmware

[dominik]

I tried updating firmware of my fresh WiPy 3.0 today and noticed that Pycom Firmware Update shows only WiPy 2.0, LoPy and SiPy as available board options. Quite lightheartedly I selected WiPy 2.0 and flashed with 1.10.0.b1.

Updating to 1.10.0.b1 for WiPy 2.0 made my board fail to boot with repeated Guru Meditation errors like the following:

rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

I also tried to flash from command line using esptool.py with image returned by findupgrade query for WiPy:

https://software.pycom.io/findupgrade?key=wipy.wipy%20with%20esp32&redirect=false&type=all

And I tried erasing flash using esptool.py prior to flashing, with no luck still.
Finally, I tried flashing with the original firmware version (1.7.1.b1), which didn't work and I'm either getting Guru Meditation all the time, or my heartbeat LED is solid red.

Are WiPy 3.0 firmware images different from WiPy 2.0? If so, where can I get them from?

Thanks

@danielm That was it. Thanks a ton! <3

Try to modify updater.py according to Update in the first post:
https://forum.pycom.io/topic/2097/new-firmware-release-1-10-0-b1-external-4mbyte-ram-support

I experienced repeated Guru Meditations Errors with latest FW on L01 in case it was flashed with unmodified updater.
