Flashing problem with Rasp 2 GPIO #4

trungdn commented 7 years ago

I try to flash a firmware for Adafruit Bluefruit LE UART Friend module https://www.adafruit.com/product/2479 I made the connection same as instruction. SWD (BLE) connect to PIN24(GPIO) SWC (BLE) connect to PIN25(GPIO) FCR (Factory Reset - BLE) connect to PIN18(GPIO) GND (BLE) connect to GND (GPIO)

The comment I use sudo python flash.py --jtag=rpigpio --board=blefriend32 --softdevice=8.0.0 --bootloader=2 --firmware=0.6.5

But no luck, the flash was failed Here is the log.txt

BCM2835 GPIO nums: swclk = 25, swdio = 24 BCM2835 GPIO config: srst = 18 srst_only separate srst_gates_jtag srst_push_pull connect_deassert_srst swd 0 cortex_m reset_config sysresetreq adapter speed: 1000 kHz Info : BCM2835 GPIO JTAG/SWD bitbang driver Info : SWD only mode enabled (specify tck, tms, tdi and tdo gpios to add JTAG mode) Info : clock speed 1001 kHz Info : SWD IDCODE 0x0004d414 Error: Target not examined yet in procedure 'reset' in procedure 'ocd_bouncer'

Could you please help me to find the problems? Thank you very much.

rpigpio doesnt work well with nrf52 - use a jlink! :)

I could not flash with RPi either. Would a stlink/v2 work in place of jlink?
