When programming the external hex file did you first change the device to one from the "External Flash" category?

ARM Cortex / Re: LPC 1549 - ISP options not working

What do you mean it "gets disabled"? What version are you using? If it's not the latest version then make sure to update first.

Please post more details and screenshots of the problem.

Hi all,

We have a board using NXP LPC54628J512 (512KB flash) with a 256MB external flash S25FL256SAGNFI001 (SPIFI). Our hex file is around 20MB.

We expect to program the hex file to internal flash first and the remaining part which is larger than 512KB can be programmed to external falsh.

At first, J-link emulator was used to program the hex file, the program was downloaded and run sucessfully on board. However when using Flash Magic (when programming, MCU is in ISP mode, ISP2/ISP1/ISP0 is 1/1/0), although it seemed to be able to program the hex file (after programming it showed "Finished" with green, and after clicking "ISP -> Verify" it showed "Hex File verified OK"), our program cannot be run normally. The external flash seemed not be written.

We would like to program this large hex file without emulator, is it possible to use Flash Magic to program the large hex file as J-link does? Or are there any other solutions to the problem we met? Any commnets are welcome.

Thanks.

ARM Cortex / LPC 1549 - ISP options not working

Hello Programmers,

I've been trying to flash program through FLASH MAGIC via SWD over Link2 but none of the options in ISP are working. it gets disabled after clicking any option on ISP.

What is the reason? the error is same in another board.

Thank you very much.

You need to read out the contents of flash to a hex file in Flash Magic, then program that hex file into the other device.

Note - you need to program into the same part number. Also if the device is locked then you won't be able to read the flash.
