Problem flashing WROOM board

[mausland]

Hi,

I'm looking forward to trying MoonModules. When I go to flash my ESP32-WROOM-32 board with [WLEDMM_14.5.0-beta_esp32S3_WROOM-2_M.bin], it flashes and then seems to go into a loop with the following.

[08:51:38]rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
[08:51:38]configsip: 0, SPIWP:0xee
[08:51:38]clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
[08:51:38]mode:DOUT, clock div:1
[08:51:38]load:0x3fff0018,len:4
[08:51:38]load:0x3fff001c,len:1044
[08:51:38]load:0x40078000,len:8896
[08:51:38]load:0x40080400,len:5816
[08:51:38]entry 0x400806ac
[08:51:38]ets Jul 29 2019 12:21:46

I'm not sure what I am doing wrong... Any help would be great.

Thanks,

Mike

@mausland The bin you are trying to use is for esp32S3

[mausland]

Thanks for the reply. Relative noob here, I saw WROOM and just assumed. Do you have a reco for which bin to use?

Correct - the "S3 wroom-2" is a very special board with ESP32-S3, 32MB flash and 16 mb PSRAM. It has nothing in common with "esp32 wroom" boards. Actually I'm a bit confused how @mausland managed to upload a firmware for the wrong CPU - normally esptool would complain loudly.

As @dosipod explained, any esp32 4MB firmware is good for esp32 wroom, as these boards are bread&butter i.e. nothing special.
