Missing file target/nrf52.cfg

[honyczek]

I'm trying to flash PineTime from Raspberry Pi according to README.md, now I'm at step 8) Flash the bootloader. I know there is flash protection, so I'm trying to run script/nrf52-pi/flash-unprotect.sh at first and later flash-boot.sh but there is an error:

pi@raspberrypi:~/pinetime-rust-mynewt $ ./scripts/nrf52-pi/flash-boot.sh
+ openocd/bin/openocd -f scripts/nrf52-pi/swd-pi.ocd -f scripts/nrf52/flash-boot.ocd

The target folder is stored in parent folder and its subfolders - not ~/pinetime-rust-mynewt/target/ but ~/openocd-spi/tcl/target/ - so find command can't look it up.

Hmmm we seem to be missing some steps... Perhaps you can refer to the latest instructions here:

https://lupyuen.github.io/pinetime-rust-mynewt/articles/mcuboot#select-the-openocd-interface-st-link-or-raspberry-pi-spi

There is a file scripts/config.sh that says which OpenOCD script to use. Fo Pi, the file should contain...

#  Select Raspberry Pi as SWD Programmer
swd_device=scripts/nrf52-pi/swd-pi.ocd

Then the script to flash should be...

scripts/nrf52/flash-boot.sh

Instead of

scripts/nrf52-pi/flash-boot.sh

May I know where you got the instructions? I will have to update that doc. Thanks!

I'm following description on the https://github.com/lupyuen/pinetime-rust-mynewt page. I suppose its text from README.md

I have updated the doc. Thanks!

Closing this issue because pinetime-rust-mynewt has been revamped for educational use.
