Hi,
I have a custom board which should support auto program.
When I try to flash it enters download mode correctly but soon after seems to reset board and download will abort.
Would I need to disable RTS/DTR (SEN_PWR_EN/CHIP_EN) lines in flash programming software?
any help/hints appreciated
Hi
custom board with RTL8735BDM Module
I would like to add that flashing works if I remove DTR and RTS lines from my Programming dongle and use CHIP_EN and PWR_EN Buttons.
regards
Hi @andf,
Currently AMB82-Mini do not support auto flash feature yet, so I’m not too sure how to help you at this point…
You mean to not press the two buttons like how AMB82-mini does it now?
Thank you.
Hey,
since it’s a custom board, did you connect PWR_EN/CHIP_EN to DTR/RTS directly or through a flipflop? Auto flash normally requires two npn transistors to work.
Unwanted reset by the Software could also happen, but normally only on first connecting.
Hi @andf,
Would you mind sharing your board’s electrical diagram / schematic diagram? May I know what is your use case for this?
Thank you.
