Re: Correct circuit for sd card

Hi @rudi, would you confirm if 10K pull up still required for SPI MOSI pin as per the link from @ESP_igrr. I am using the TTGO Micro ESP32 module and I want to connect the MicroSD card to enable firmware updates from it.

Thanks

Glenn

@ESP_Sprite

How can one JTAG debug when SDCard is attached to the same pins as it is in Espressif WROVER and Olimex EVB designs??

Stop. make: *** [/home/Glenn/src/esp-idf/make/project.mk:378: coap-build] Error 2 ...

Re: NES emulator on an ESP32

Okay so I looked more closely at the change documented by Rudi above and the back-light works as expected. :D

Re: NES emulator on an ESP32

So after some googling i found and old workaround from ESP_igrr that forces the flash to be setup for 4MB. SPIParamCfg(0x1540ef, 4*1024*1024, 64*1024, 4096, 256, 0xffff); The game finally starts now but the back-light will not come on. When I press the enable button the back-light comes on momentari...

Re: Transparent Wi-Fi module with RMII input

@ESP_Sprite Appreciate the update. While PoE not something I am looking at for the short/mid term, I can understand why the team would want to hold off and include it.
