Hi folks,

I managed to brick the PADI beast after a few brave OTA experiments. GC0 recovery method helped me several times but finally it's dead and not booting into Default Image anymore.

I'm going to use raspberrypi's native SPI/JTAG interface to program/debug PADI. 

Am I right in connecting this like? 
JTAG name / PADI / PI pins
JTAG_TRST - GE0  - GPIO 7 or 8 (tap reset)
JTAG_CLK   - GE4  - GPIO 11/SCLK
JTAG_TDI   - GE1  - GPIO 10/MOSI
JTAG_TMS  - GE3  - GPIO 25
JTAG_TDO  - GE2  - GPIO 9/MISO

I suppose PADI doesn't have dedicated system reset pin, right?

I was looking for existing board/target config files for PADI, is there anybody walked this street already?

Thanks

not sure if you have seen this before.

Thanks! Sure I saw it and am trying to follow. The picture has no device reset pin assignment, only JTAG_RESET.
