I'm trying to program a custom PCB with a KL03 using blhost.
I've got 3 boards assembled of whom 2 are working. One board hasn't been programmed (factory new) but reports that it is secure.
I do not seem to be able to erase the chip using blhost.
The device seems to be working because the response to the "get-property" commands seem OK.
When I try to erase the device using the "flash-erase-all-unsecure" command I get response 10004.
Anyone any idea of what might be the problem?
