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

@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??

Seems like I make one step forward and then step back again. After updated esp-idf to the latest code i get this message $ make flash make[1]: *** No rule to make target 'libcoap/src/address.o', needed by 'libcoap.a'. Stop. make: *** [/home/Glenn/src/esp-idf/make/project.mk:378: coap-build] Error 2 ...

Okay so I looked more closely at the change documented by Rudi above and the back-light works as expected.
I looked at that last night but it was late - that's my story ...

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...

Hi it is set for 4MB. I also tried a make clean and then a rebuild but no joy so far.

Hi Rudi, The ESP32-WROVER-KIT V2 will upload the latest code Glenn@playpen MSYS ~/src/projects/esp32-nesemu $ make flash /home/Glenn/src/esp-idf/make/component_common.mk:1: Deprecated feature: No longer necessary to include component_common.mk from /home/Glenn/src/projects/esp32-nesemu/main/compone...

Is this reference design an add on to one of the existing dev kits or an all in one design?

@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.
