Hello @chewitt
I just sync patches from your LE repo: https://github.com/chewitt/LibreELEC.tv/tree/amlogic-master/packages/linux/patches/amlogic
But it seems not very stable, sometimes work but sometimes not and I got the error:

Yes, i’ve reported the same warning splat here https://patchwork.kernel.org/cover/11286567/ and I’d like to run some tests with VIM3L and some other G12A and G12B devices I have to see if the issue is related to board or SoC or … something else. I’m travelling with work so it will be a couple of days before I can do much testing.

Load firmware failed, and mmc0 report an error, if I remove sd-uhs-sdr50 in mmc0 it works.
Anyway, have a nice vacation.

I added https://github.com/chewitt/linux/commit/85c6fd04de6741d4751930968ab7e1a13d14a255 to my branch, but I haven’t seen issues with loading firmware.
I do see errors in dmesg after connecting to a network:

Yes, If I remove sd-uhs-sdr50 the firmware loaded well.

I’m using https://github.com/chewitt/linux/commits/amlogic-5.5-integ as a working kernel branch. I sync the commits to patches in https://github.com/chewitt/LibreELEC.tv/commits/amlogic-master every few days, but it’s usually behind. Everything is “work in progress” at the moment.

Some update:
Linux 5.5-rc2 + AP6398S test results:
VIM2: Works without errors.VIM3L: Works without errors.VIM3: Works with some errors. (Need remove sd-uhs-sdr50)Edge: Works without errors.
Stability still need to be confirm.

yes wifi works! but for VIM3 is not usable - very unstable - slow speed , gaps , lags, lost connection, and error!
NOTE: all another boards works - OK !

The X96-Max box I have (S905X2) uses BCM4356 but shows the same issues http://ix.io/24YV so I think there’s an issue with SDIO somewhere.

Neil says “Oh I see why, we should disable sg_support since we support only a single sg…” but he’s on vaction for 14-days over Christmas and New Year so unless that means something to you (or anyone who writes code) further investigation might take a while.

OK! i have done test for all VIMx boards
VIM3 notes
all errors possible to fix (but with lost some speed performance ) im not very competent at this linux drivers parts - maybe smbdy can make it more properly and elegant
yes we need remove this one from dts sd-uhs-sdr50 , but its not enough ( AP mode - not stable )cap-sd-highspeed - dont remove this node!!! ( this param make speed limit to 50Mhz - !!! 100Mhz not stable!!! )
/sys/kernel/debug/mmc0/ios:clock: 50000000 Hz
/sys/kernel/debug/mmc0/ios:actual clock: 50000000 Hz
( but dts still must have this one max-frequency = <100000000>; )
and we need apply next my patch
NOTE: i think something wrong with mmc host driver for VIM3

G12A and G12B devices have a chipset bug that impacts SDIO - I see the same issue on a GT-King Pro and X96-Max box (both using BCM4356). GXL/GXM and SM1 don’t have the chip bug. I’ll pick the patch into my branch as a tempoarary workaround (tagged as HACK) but it needs to look for the g12a/g12b SoC compatible rather than board as the issue is not limited to VIM3. The real fix needs to be done in the mmc driver not brcmfmac, but that will take time due to Christmas and New Year.

The previous patch is flawed due to my general ignorance of c++ … it always evaluates to true so the hack is applied to all hardware. Below is an alternative approach that forces values in the mmc driver when amlogic,dram-access-quirk is in the device-tree, which only applies to g12a and g12b:
