nuttx

[bingw]

hi:

   It didn't work that I run the LPCXpresso54628 board os demo of nuttx at LPCXpresso54018 board platform.I changed the board configuration of PLL frequency from 220MHz to 180MHz and spiflash address at 0x10000000 and RAM address at 0x20000000 and other related memory address,but the nuttx looks doesn't work which the nsh can't output.

What could I do for the working of nuttx demo on LPCXpresso54018 platform?

Thank you!

I would not expect the LPC54628 port to work with the LPC54018.  It is not just a matter of configuration. My understanding is that there are difference is the clocking logic.  That would require some small design enhancement to the core LPC54xx logic.

Hello,

Unfortunately,  NuttX has limited support on our side. For RTOS software we can provide the FreeRTOS examples located in the MCUXpresso SDK. https://mcuxpresso.nxp.com/en/welcome

Sorry for the inconvenience this may cause you.

Best regards,

Felipe

I download the .bin file with J-Link as the picture above show.

The flash.ld file is as same as LPCXpresso54628 except memory address.

The nsh configed to USART0 and enabled,but it looks not run to the __start() function.
