Also esp-prog debugger UART connect RX -> RX and TX -> TX

not TX - RX and RX - TX

OK, in case anyone is trying to flash Lyrat 4.3 via external RXO TXO UART, Yes you need to take off the R7 and R11 by the USB-UART chip. I obviously need to set the flash size in some config somewhere as its only auto detecting size every other time. as you can see below the 1st attempt fails and th...

does anyone know if its possible to hook up ESP-prog to lyrat 4.3 board for flashing over UART pins ? I have finally got OSX to unload the FDTI serial driver and can access both serial ports. 1 for JTAG and the other for serial flashing. The ESP-prog is flashing lights when I MAKE FLASH but the lyra...

ok, I tried again using OSX and eclipse and it worked. I actually had 2 problems. The 1st was I had CMD and CLK pins from the SD card socket wired up to other hardware. I had wrongly assumed the switches disconnect the SD card lines and enable the JTAG socket ! The other problem must be windows fire...

I tried slower adapter speed as I have regular jumper wires between ESP-prog and lyrat 4.3 C:\Users\ben>openocd -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp-wroom-32.cfg Open On-Chip Debugger 0.10.0-dev (2018-09-20-12:54) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/...

Hi, I have connected an ESP prog to the Lyrat 4.3 board. I have set the JTAG switches. Enable JTAG DIP SW Position 1 OFF 2 OFF 3 ON 4 ON 5 ON 6 ON 7 ON 8 n/a I have followed this simple guide to setup Visual Studio with the blink template; https://github.com/botofancalin/Esp32_debug_template I am ru...

OK, thanks. I'll stick to using the SDCARD IO pins as I might need JTAG debugger EDIT: Just in case anyone else is looking to add a SPI port and use JTAG debugger , IO12 and IO13 ( SD card slot CMD and CLK) are used by JTAG so best scavenge a few GPIO pins from switches or touch pads that are 3.3v c...

does anyone know what the pins are used for on lyrat 4.3? Are they unconnected because they are 1.8v only ? SPI_SD0 SPI_SD1 SPI_SD2 SPI_SD3 SPI_CMD SPI_CLK the TF_CARD uses these pins shared with JTAG connector IO15 IO14 SD_IO13 SD_IO12 IO4 IO2 IO34 I removed the SD card and removed the 10k pullups ...

Hi Chris,

I just wondered if you had any luck getting SPI working over JTAG pins ?
Did you have enough for CS pin to ?

ok great , I'm pretty sure I can get away with less than 20mhz SPI as long as I can get DMA working so I'll try to use the multiplexer and repurpose the JTAG pins on the lyrat 4.3 board. no idea yet where the JTAG GPIO pins are defined in esp-adf but should be able to find them. hopefully I'll have ...
