Re: ESP32 C3FN4 not detecting

Hi I use a LDO as a power source. 3.3V is stable I think the issue is with GPIO8 and GPIO2 not be pulled up with 10K to 3.3V, as i have connected it to an LED. As per ESP32 C3 TRM, page 182, Table 7-2, GPIO8 and GPIO2 states should be high when the device is booting out of reset. Will try this assum...

ESP32 C3FN4 not detecting

Hi We have designed a board using ESP32-C3FN4 We are not able to detect the chip. We have provided EPSON 40MHZ crystal [FA-238]. The hardware guide for ESP32 C3 mentions that we have to choose a component in series with XTAL P pin, but does not recommend any value. Also there is a 499ohm in series w...

Re: Flash read error on ESP32 PICO D4 SIP module while programming on arduino

Hi

Thanks for the suggestion, one of the IO pins was connected to the pin muxed with the embedded flash.

Removing the 0ohm on that IO got the board working.

Thanks for your support. Appreciate it
