LPC54605 ISP UART

[Mateusz_K]

I am using ISP through UART on LPC54605. I follow the procedure described in the User Manual, that is: 

- send synchronization char

- send "Synchronized\r\n"

- send freq

After all this commands I am getting expected response. How ever, when I send Unlock command I am receiving ERR_ISP_PARAM_ERROR return code. Unlock commands which I am sending is structured as: 

"U 23130\r\n"

Procedure, which I am using works on other LPC devices, such as LPC11Axx.

Hello, my name is Pavel, and I will be supporting your case, is there a possibility that your device is locked, could you try to use the SPSDK and on this use BLHOST to read if the flash is lock.

I won't install it, but I am sure that device is not locked. ECRP region in flash is empty, I can reprogram and erase the device using SWD

I mean, I will try to install it, meanwhile: UART communication looks like this
