ordered st-link v2 via webshop nearby.
Delivered this morning.
Connected, started the software, disabled the read protection.
Restarted the pi-star and flashed the hat again.
All ok now !
Nigel, thanks for your support !

Looks like I too have a duplex board that has been locked. A little bit sneaky of them (might not be intentional) but not a big problem to rectify.

Oh how embarrassing! I didn't even look at the JP1 status! But I think that you are right! Silly me

Sorry to drag this back up - but the tools to unlock them are also on Pi-Star's image
Code: Select all
pi-star@pi-star(ro):~$ sudo stm32flash --help
stm32flash 0.5
http://stm32flash.sourceforge.net/
stm32flash: invalid option -- '-'
Usage: stm32flash [-bvngfhc] [-[rw] filename] [tty_device | i2c_device]
-a bus_address Bus address (e.g. for I2C port)
-b rate Baud rate (default 57600)
-m mode Serial port mode (default 8e1)
-r filename Read flash to file (or - stdout)
-w filename Write flash from file (or - stdout)
-C Compute CRC of flash content
-u Disable the flash write-protection
-j Enable the flash read-protection
-k Disable the flash read-protection
Note: I have *not* had the need to use this myself, so I wont say that I know it works, but the options are already there, you should not need to use a soldering iron, fight with software or get any kind of programmer
If anyone finds out that I am wrong about this, please tell me

Sorry to drag this back up further, but I had the same issue with my mmdvm-hs-hat clone
edgetriggered from the m17 discord directed me to try stm32flash -u
I was able to use the stm32flash software on the pi-star through the browser ssh to get it going
I used the commands from install_fw_hshat.sh
At first I couldn't get -u to work. It always returned NACK. Then I tried -k and completed then I tried the -u after that and it worked.
These are the commands I ended up using This may not be correct for everyone, this is just what I used.
Code: Select all
sudo killall MMDVMHost >/dev/null 2>&1
sudo stm32flash -k -i 20,-21,21:-20,21 /dev/ttyAMA0
sudo stm32flash -u -i 20,-21,21:-20,21 /dev/ttyAMA0
sudo pistar-mmdvmhshatflash hs_hat
