Hello, I tried to run the following command on my nRF52832 today and it reported an error.
The operation before the error was: I enabled APPROTECT, and when my colleague used JLink to connect to it, a pop-up window asked whether to unsecure it. After he chose Yes, I could no longer use nrfjprog to successfully execute any commands.
There is a certain probability that the chip can be connected with jlink, but the connection is very unstable, about four to five times before it can be successful, other times I will occasionally remind me that the chip is secured.
I tried to burn it into the new firmware and it also reported an error:
****** Error: Failed to prepare for programming. Could not preserve target memory. Unspecified error -1
And when I use mem8 in Jlink to read some memory, all of them are just 0xFF
