Re: ESP32 WROOM 32E module programs okay but doesn't run

That explains why I initially thought the ESP PROG should have returned the EN pin to logic high. Still it works with the cap on GPIO0. I have to wonder why there are empty footprints for the RC network for EN and GPIO0. For EN the functionality is obvious, but why then for GPIO0? I don't have an is...

Re: ESP32 WROOM 32E module programs okay but doesn't run

I got it working. It was the missing RC network on EN. Its a really messy hack to make it work. But I was expecting another rev anyway. BTW the cap on GPIO0 is okay. The ESP-PROG has one. I see the flash is running in DIO mode but I programmed it in QIO mode. Should I change the running mode to QIO ...

Re: ESP-WROOM-32E defective pull-ups

Well the external pullup shouldn't hurt. I put it by default on my design and I can flash fine, but I'm having problems because the flashed program won't run for very long. I've posted that in another thread. Waiting for it ot be approved.

ESP32 WROOM 32E module programs okay but doesn't run

I've created a custom PCB with a ESP32-WROOM-32E-N16 module. I can program the module using the ESP-PROG adapter, but the program either doesn't run or crashes after a short while Its a simple hello world in a loop program written using Arduino. I'm using the same settings (default) except flash siz...

Re: ESP32-DEVKITC and ESP-PROG

So I accidentally found out what the problem is. I also have a header connected to Serial0 for a TTL serial adapter. I programmed a loopback on Serial0 and it works using the onboard serial connection BUT NOT the TTL serial adapter. I can send data out from the ESP32 (ie TXD0 works) but the RXD0 doe...

ESP32-DEVKITC and ESP-PROG

I am not able to program the ESP32 with the ESP-PROG using the Arduino IDE. I can program the board using the built-in serial port on the dev kit. So its probable the settings other than com port do not need to be changed. If I connect the ESP-PROG to the dev kit, open the programming serial port, a...
