I would like to create a SBL using DFU for the LPC51U68.
Has anyone done this?
Did you use AN12327 or AN12037 (11u6x) or one of the usbd_rom_dfu_composite example projects like for the LPC4370 as a base ?
Just wanting to know I'm on the right path before I spend any more time on it. Tried a bit of all 3 but all have issues.
Any code or examples would be appreciated. I find the CMSIS code does not port easily and I'm thinking maybe LPCopen and a new MCUxpresso project with mex configurations the way to start but not sure...
How about your this case now?
Sorry I just checked your private massage. Recommend reply on the case thread next time if there is no secret, because we hard find the private message. And we can give help on the thread reply more quick then private massage.
AN12327 if for LPC55xx, do not very suit for LPC51u68.
You can refer to AN12037 or https://www.nxp.com.cn/docs/en/application-note/AN12689.pdf (https://www.nxp.com/docs/en/application-note-software/AN12689SW.zip ).
And you can also use ISP mode update your firmware.
