Custom PCB does not work
Posted: Wed Jun 17, 2020 6:40 pm
Hey folks,
me and my colleague made a PCB using the ESP32-S0WD. We are using a FTDI231XS USB to UART Converter to program the ESP and an additional external Flash (W25Q16JVSNI). Regarding PlatformIO we can upload our Program without any errors and are just using 16.5% of Flash and 4.9% of RAM but the Program is not working at all and not even a Testprogram is printing any Testmessages. Even so same Code is working on the Wroom Dev-Kit.
All we have changed till now is that we have removed C27 cuz we had no propper levels on the Chip_PU.
The Programming Interface shoulda work properly but Iam not sure about our Flash. Even so its constantly transmitting/recieving data and toggling WP, CLK and CS.
Please help me out. TY!
