Hi,
We have a core processor that runs embedded Linux, connecting to LPC55S1x via SPI. When we have a new image for the LPC55S1x. The image is stored in core processor. What is the suggested way to update LPC55S1x FW?
Thanks,
Winston
Hello @yangao
1) You can development a secondary bootloader with SPI. Core processor send new image to LPC55s1x through SPI. Then use secondary bootloader program new image.
2) Boot ROM of lpc55s1x support ISP_SPI mode. Also can use this function, While this need PC send image to MCU.
