Running NuttX on LPCXpresso54628 OM13098

Today I tested NuttX running the LVGL demo on LPCXpresso54628.

Here you can find the steps needed to get it working.

First compile the firmware to create the nuttx.bin:

$ ./tools/configure.sh lpcxpresso-lpc54628/lvgl
$ make menuconfig
$ make

Now you can flash the firmware using JLinkExe on Linux.

You can use the LPC54608J512 even to flash the LPC54628:

$ sudo JLinkExe -if SWD -device LPC54608J512

Type "connect" to establish a target connection, '?' for help

Run “connect” command:

J-Link> connect
