LPC54018JxM Program flash using UART

[mohd_]

Hi,

Is it possible to program the flash on LPC54018JxM using UART?

As I know, there is no command for Copy RAM to Flash in UART ISP commands, is there any other way to program the flash using UART? I tried using the Write to RAM command, but the code will disappear upon reset.

Thank you.

Hello mohd_,

You can using blhost with UART isp port to program, detail steps please refer to:

Hi @Alice_Yang ,

Thank you for the information.

For anyone who want to program lpc54018 flash using UART, you can try following ways;

• Program the flashloader.bin to lpc54018 RAM using UART ISP command. 
• Close the serial terminal then open command prompt to use blhost.
• Use below blhost commands to program the flash. Replace COM7 with your serial port name.
  • blhost -p COM7 -- get-property 12
  • blhost -p COM7 -- fill-memory 0x0000b000 4 0xc0000004
  • blhost -p COM7 -- configure-memory 0xa 0x0000b000
  • blhost -p COM7 -- get-property 25 0xa
  • blhost -p COM7 -t 100000 -- flash-erase-region 0x10000000 0x100000
  • blhost -p COM7 -t 100000 -- write-memory 0x10000000 led_blinky.bin
  • blhost -p COM7 -- reset
• Done!

Best Regards.
