on-board SPI flash chip question

Postby nickn » Fri Sep 26, 2014 4:14 pm

I'm wondering if the flash chip serves any particular purpose or if it's just another item to experiment with?

XMOS devices can boot from SPI flash. Flash the firmware using xTIMEcomposer tool or using xflash command from the command line to the external SPI flash device, power cycle the device. You will see the flashed firmware boots up when the device is powered up.

Also, you can SPI flash to write upgradable images (used for performing infield update). The flash device can also be partitioned as boot partition and data partition and can be accessed by using simple APIs, Have a look at the following url for details on partitions:
