I found this gem which does just that:

However I haven't tested it. Please make a public fork or pull requests for any improvements you make too!

Interesting! Thanks for the insight.

Also what is ECO? I can’t find a definition - external crystal oscillator?

From what I've seen in esp-idf, LDO 2 defaults to 1.9v, and powers the internal PSRAM - so if the combined current draw, and the 1.9v voltage level are OK, I recon that would work. What flash IC are you thinking?

Relevant kconfig options appear to be ESP_LDO_VOLTAGE_PSRAM_1900_MV, ESP_LDO_CHAN ...

I would also love to see an update! Currently thinking whether to pick an S3 or a P4 for my next design.

Ok I think I worked it out. I used the ESP32-S3R8 chip, which I have just realised doesn't have internal flash, and so perhaps the behavior we are seeing makes sense as there is no flash chip in the system - as that's where the error occurs.

Looks like someone else had a similar experience ( https ...

My goal here is to be able to flash my custom PCB, which I have not been able to do yet.

I had thought that I could use USB jtag on the esp32s3 board to get it into 'download mode'.

If I run this python code snippet, implementing the approach in section 33.4.2 of esp32s3 TRM v1.4:
