yes, it came protected, mass erasing it unprotected it. with espruino you can check status via peek32(0x10001208). espruino does not lock it. if locked via APPROTECT it can be also unlocked in software via erasing UICR registers (e.g. from Espruino)

not sure what "locked" means for you but if softdevice is not starting and you started from nordic devboard configuration you should remove definitions for those boards (e.g. like PCA10040) so it does not include board specific files from SDK and also it may be due to missing external 32kHz crystal. those devboards have it but it is optional component that BT5032A does not have. check source/configs for setting that include _CLOCK_LF_SRC , it should be set to 0 = internal RC to have it working on E104BT5032A, not 1

e.g. here https://github.com/lab11/nrf52x-base/blob/master/sdk/nrf5_sdk_16.0.0/config/nrf52832/config/sdk_config.h#L12640 and more places
see also difference here https://github.com/espruino/Espruino/blob/master/targets/nrf5x/bluetooth.c#L2344 for RC you also need to configure those two 'ctiv' calibration values 16,2

this should of course not affect SWD functionality and the APPROTECT lock in any way

My goodness! It was the fricking internal oscillator.... I can’t express how grateful I’m for all your help. It was driving me nuts!
Well, you learn something new every day, ;)

The SWD problem should be another story, but at least now I can flash my own binary.

Again, thank you very much indeed!!
