ESP32-S3-WROOM-2 based board - unable to setup with tinyuf2

[ishahak]

I have a simple custom board very similar to devkitc, based on ESP32-S3-WROOM-2-N32R8V | Flash: 32 MB (Octal SPI) | PSRAM: 8 MB (Octal SPI)
not identical because I have only one USB connected to the UART, instead of two in the devkitc, and no neopixel hardware.

I tried for two days to build an tinyuf2 to it, without success. it is crashing with assert.

this is the log:

I went to debugging the C code and found out that the failure is in lib/esp-idf/components/esp_system/startup.c

Code: Select all

	do_core_init() within start_cpu0_default()
		fails on assert because of bad return code from esp_flash_init_default_chip()

my sdkconfig is copied from here:
https://github.com/adafruit/circuitpyth ... /sdkconfig

because it is the same chip.

I was trying so many options without any success.
I would appreciate your help so much!!

thanks!

Actually, loading the official pre-built tinyuf2 of esp32s3-devkitc-n32r8 from https://circuitpython.org/board/espress ... tc_1_n32r8 on a real devkitc board brings the very same result:

(same as above, copying the last lines only:)
I (300) spi_flash: detected chip: mxic
W (304) spi_flash: Detected flash size > 16 MB, but access beyond 16 MB is not supported for this flash model yet.
I (315) spi_flash: flash io: qio

This is really weird because in the past I could successfully install tinyuf2 on the devkitc board (I still have one working!)
Any idea please???

I believe the crashes were due to a missing config:
CONFIG_ESPTOOLPY_OCT_FLASH=y
