Suck at booting...

[bsodergren]

I can no longer flash new firmware to the e3p board. I can connect to the board using openocd, raspberry pi and connecting to j1 on the board using pins 24-25 to map to DIO/CLK

my openocd config

adapter driver bcm2835gpio
bcm2835gpio peripheral_base 0x3F000000
bcm2835gpio speed_coeffs 194938 48

# SWD GPIO set: swclk swdio
bcm2835gpio swd_nums 25 24


transport select swd
adapter speed 100

set CHIPNAME stm32f1
source [find target/stm32f1x.cfg]

#swd newdap chip cpu -enable
#dap create chip.dap -chain-position chip.cpu
#target create chip.cpu cortex_m -dap chip.dap

set WORKAREASIZE 0x2000

#reset_config srst_only
#reset_config  srst_nogate

#adapter srst delay 100
#adapter srst assert_width 100

init
targets
#reset halt

output from openocd

sudo openocd -c 'set ENG_MODE 1' -f interface.cfg
