RTCWDT_RTC_RESET endless loop

[pacmac]

I just received some ESP32-WROOM generic development boards and after make, make erase and make deploy and restarting the device it is stuck in an endless loop:

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0x00
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:QIO, clock div:2
load:0x3fff0008,len:8
load:0xffffffff,len:-1

Any suggestions on what the cause may be ??

You might need to use FLASH_MODE = dio and FLASH_SIZE = 2MB config settings in your GNUmakefile.

Thanks so much, yes indeed that solved it, I now have the REPL :-)

Also make sure watchdog is disabled if your image doesn't support it.
