ESP-PROG flashing problems

[eidetech]

Hi,
I have an ESP-PROG that I want to use for programming and debug of my PCBs with ESP32-S3 on. I have a USB interface for flashing as well on the PCB, which works without any problems, and I am able to flash the PCB ok. Using the ESP-PROG card, I can read the serial feedback from the PCB with the default hello world on it, but I am not able to flash it from ESP-PROG. I have tried pressing BOOT and then RST and then letting go of RST so that it is in download mode, but then when I press the flash button in Eclipse, it resets the board, and flashing fails...

I have tried watching a couple of videos on YouTube and doing a bit of googleing, but it seems that most people only use the ESP-PROG for debug via JTAG and not for flashing via serial...

Can anyone assist me in how I can get the flashing via ESP-PROG to work?

As you decribe, if download fails because when you press the flash button in Eclipse, it resets the board without boot GPIO to low? You could connect boot GPIO directly to low and see if it could help.
