1. The RG351V second microSD slot support

2. The RG351MP support (different from RG351M)
   - display resolution is 640x480 (The RG351M is 480x320)

   - no internal wifi (The RG351M has internal wifi)
   - no vibration device (The RG351M has vibration device)

3. Audio volume changing support for OGA and OGABE

Add to your issues that atm there is no way to access sound volume settings and sound is always max vol

For which device? Volume control did work for me I think.
BTW it is useful to add wifi dependencies/packages on all these devices. Some shipped without wifi but it could be installed (there is space in the PCB and you can buy the chip and solder it, it's quite easy in fact), so might be a good idea to keep the drivers (wifi worked for me IIRC). Plus some have a USB_A port so you can always plug a wifi dongle.

Thanks for your work, pretty amazing!

Oh side note: in the older v3 branch we had some devices merged toghether, notoriously the original OGA devices. Their u-boot has a version check that allows testing which device you are running on and dinamically choosing the right DTB. I take this is not possible now? I see each platform has a single dtb associated with it (instead of multiple DTBs for instance). Could be an easy way to save some space and bandwidth.

@Ntemis

• HARDKERNEL ODROID-GO Advance
• HARDKERNEL ODROID-GO Advance Black Edition
  Both devices have no volume control switch.
  Maybe you use HARDKERNEL ODROID-GO Advance. Correct?

Both devices have I - VI bottons.

My opinion is below.
II changes to Volume Down.
IV changes to Volume Up.

Current buttons assignment are :
I = L3, II = gun_trigger, III = SELECT,
IV = START, IV = gun_offscreen_shot, VI = R3.

@davidgfnet
Many thanks for your detailed information.
And your merged commit is very helpful.

I remained the device detection patch in u-boot.
Probably it will be working with boot.ini that has device detection.
But, I took to create the each device(dtb) image.
By this, user is easyly able to select proper image by image name I think.
I don't know it is good or not.

I can't confirm on ODROID-GO Advance (1st gen).
Could you please confirm this?

[ShigeakiAsai]

I got HARDKERNEL ODROID-GO Advance ver1.0 with HARDKERNEL USB wifi dongle.
This dongle doesn't work. because kernelconfig is disabled for this USB wifi dongle.
this is needs update too.
