RT600+KEIL5+JLINK(FLM flash programming issue)

Jokerufo — Thu, 25 Dec 2025 02:25:15 GMT

HI,

I am developing audio product on RT685-AUD-EVK, i use KEIL5 as devl tool, there are some issues when i use arm algorithm FLM file to program flash, attachment is FLM i used, please help me to solve those issue, thanks.

1)MIMXRT685-AUD-EVK

2)Program LPC4322 to jlink MODE

3) JLINK CAN ACCESS RT586 chip

4)keil program flash incounter can't halt CPU

Hi @Jokerufo ,

I tested with on board JLink and it works.

First, ensure that the FLM you selected is the two with the FlexSPI_B suffix. If this step is confirmed correct, put the board into serial download mode and use SEC or MCUBootUtility to erase the Flash before attempting reprogramming.

Best regards,
Gavin
