Note

Note: Since not all of the options are exposed by menuconfig, appending them to configs/sr_cn913x_cex7_defconfig before running make sr_cn913x_cex7_defconfig is the easiest.

Deploy

From Linux

  • To microSD

...

Code Block
dd if=flash-image.bin of=/dev/sdX conv=sync

  • To eMMC bootYboot

Since the eMMC is soldered to the board, this procedure has to be done on the device itself after booting into a Linux system first. Please note that as with the eMMC data partition, the Boot ROM expects to find the bootable image at the start of the partition without any offset.
