LPC55S69 Execute ISP Command

awseiger — Thu, 14 Jan 2021 18:50:36 GMT

Hello,

When I send the "execute" command to the ISP ROM bootloader, the LPC55S69 responds with "Command is Not Supported (0x2716). The user manual claims that this is a supported command, and "get-property available-commands" shows that execute is a valid command. What am I doing wrong? I am trying to execute a program that I have loaded into RAM via an SB2.1 upload.

Thanks,

Alex

Hello Alex,

Do you use blhost ?

Could you please show all your steps and all the commands?

If you want to use secure boot, recommend you refer to this application note:
