Reply To: Cannot change GPU memory setting

Just reloaded from scratch on one of the boxes.

Box is Raspberry PI 2 with HiFiBerry Digi+ connected via LAN

1. Win32DiskImager to put m2p_rpi_default_244_wps_ap_expand.img to MicroSD card
2. Insert card and reinsert power lead
3. Login to http://max2play
4. Select HiFiBerry from prompt window, driver installs
5. Select Digi+ on HiFiBerry tab and save
6. Switch to Raspberry Settings tab, no GPU memory size displayed, cannot see debug info
7. Switch to Settings/Reboot tab
8. Activate with email address
9. Switch to Raspberry PI Settings tab, GPU memory reported as 128, DEBUG Information visible
10. Change GPU ram setting from 128 to 16 and Save
11. Reboot needed message displayed, but GPU ram setting reading 128 again
12. Switch to Settings/Reboot tab
13. Reboot
14. GPU ram still set to 128
