How to enter flash mode

Hold Accept and Power buttons to enter fastboot.

Issues

  • It's not possible to control screen brightness/disable screen;
  • The keyboard backlight brightness is very low.

Installation

Install pmOS on microSD with pmbootstrap install --sdcard /dev/mmcblkX where /dev/mmcblkX is path to card that can be found with lsblk. Insert card in device, enter fastboot as written above and run

pmbootstrap flasher flash_kernel
fastboot reboot

fastboot boot doesn't work as intended.

Kernels

This section may be interesting for those who want to port postmarketOS on SP7715GA device. I've tried some downstream kernels and there are my findings:

  • bigzz/sc7715-kernel: boots, but doesn't support SDCardFS.
  • BLU kernel: being used for this device as the best suiting kernel.
  • Blade AF3 kernel: has building issues with autotst driver.
