Sprite, you hero your reply directed me to the problem.
Flash voltage was wet wrong., blew the e fuses and it's now abled to be programmed. Perfect!

Thank you.

IO3 is also mentioned as a bootstrap pin, i completely missed this in the data sheet, this in the current design is pulled high permanently from Power on. Could this be the issue? the old design did not have this issue.

Removed the resistor to break the circuit and its not changed anything

Ive since further looked in the data sheet and found the strapping pins for the S3 variant are 46 and 0, 46 on the old board didnt have anything on, was disconnected and i assume left floating. It is now connected to an RGB LED with a 470 Ohm resistor. Beginning to think this could point to the ...

Hi,
Im wondering this, we checked the IO12 and its low on boot, as is the old board so i was hoping that there was something obvious there. But not sure, ive since tried a second and third board and now get a different behaviour.

Within VS code with Platform IO i get the MD5 of file does not match ...

Hi All,

I cannot seem to program an ESP32-S3-WROOM-1 on a custom PCB. Its a re spin of a productionized design, so I'm lead to believe the programming connections are correct.

There is no UART buffer chip on board, so this shall have to be done using the USB, ive followed the steps of putting it ...
