Cant Flash Copy of Devkit
Posted: Fri Feb 14, 2020 9:17 pm
Hi,
We just spun our first board and are having issues flashing the esp32 WROOM 32D module. The USB circuit is the exact same as the devkitc v4 (https://dl.espressif.com/dl/schematics/ ... v4-sch.pdf).
The logs of the devkit flashing and our board flashing are below- our board gets hung up after the board is recognised and after the first write.
DEVKIT FLASHING (working)
MY BOARD (not working)
Let me know what you think this could mean, Im at a loss right now. On both boards, the boot and enable pins move correctly and it seems like even on the devkit it is recognizing the esp32 chip at least somewhat.
