Hi I am able to load the nrf9151dk_at_client example hex on my custom dev board . I try accessing the AT commands and I can very easily get the responses. I want to install custom certificates & priv keys through Certificate Manager But as soon as I try to load it, I get Unable to Write TLS Credential. I did try updating the CERTS through AT%CMNG command and they too keep giving me some errors or are hanging. Not sure why it perfectly works on a dk but not on my custom board.
