LPC1830 UART ISP to write Flash

[kensu]

Hello

Can LPC1830 write data from RAM to FLASH by ISP command?

My LPC1830 use SPIFI interface flash 8MB for code image.

I want to try UART ISP upgrade FW.

After I check the user manual. It look like the LPC1830 cannot support RAM to FLASH by ISP command because LPC1830 belong to flashless part?

Is my understanding correct?

Regards

Ken

Right. The flash programming ISP is available for parts with on-chip flash. A reduced set of In-System-Programming (ISP) commands is supported for flashless parts. For detail. see LPC18xx UM.

Have a nice day,

Correct. ISP only support *internal* flash, and since there is no internal flash, you cannot program it.
