what would cause repeated RTC watch dog reset? (RTCWDT_RTC_RESET)

[RMandR]

I programmed a custom board with ESP32-WROOM-32 module on it. ESP_PROG connects and flashes without issues but the Monitor output is the repeated "error" below.

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:2
load:0x3fff0018,len:4
load:0x40080764,len:33006

What have I not done right?

What bin files did you flash and with which software?

I compiled the Hello World sample using "make flash monitor".

It did however, go through a bunch of config questions to which I picked all default values.

I am getting this error in my esp32 devkit v1
How to solve it?
I am using arduino IDE for programming the esp32.

I seem to remember having an esp32 a good while back which was giving an error something like this, I discovered that if I changed "flash frequency" to 40mhz and it then worked - worth a try.

Any kind of problem like this I find the first thing to check is the power supply as if it has a problem with this you will get all kinds of weird errors/restarts etc..
This is advice I have not taken myself several times and as a resulted wasted hours on a wild goose chase - lol

I have tried 40Mhz with 115200 baud rate but no luck!
