Using the Debug Mailbox with IAR tools

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.

Hi @rony243 

The ERR_ISP_PARAM_ERROR return code indicates that there is an issue with the parameters of the Unlock command you are sending. On the LPC54605, the Unlock command expects a specific set of conditions to be met.
