Aug 21 11:03:50 <Herrie> Tofe: Tp4G is back in business, replaced LCD and digitizer with spare I had
Aug 21 13:04:42 <Herrie> Tofe: For PPP failing to boot on 5.19 kernel, according to Megi it's likely due to camera stuff :S
Aug 21 13:06:38 <Herrie> "<megi1> two issues, maybe missing camera modules in initramfs" and "<megi1> or if danct made them builtin, then perhaps tow/u-boot without support for io voltage switching" and "> Pine64 Protocol Bot:
Aug 21 13:06:38 <Herrie> [I] <megi1> so camera will not probe and display will fail"
Aug 21 13:14:39 <Herrie> I'm not really sure what megi1 means with "missing camera modules in initramfs". When we enable it in the kernel, it should be there, no? 
Aug 21 18:05:05 <Tofe> Herrie: well, some distros have also kernel modules in their initramfs
Aug 21 18:06:11 <Tofe> so what megi says, I think, is that either the builtin code can't be initialized properly so soon, or if it's a module then maybe it's looking for it during initrd script boot
Aug 21 18:07:14 <Tofe> Herrie: so the first thing to clarify: is it currently a module? could we change defconfig to have camera as a module? and of course include the module in the rootfs
Aug 21 18:07:51 <Herrie> Tofe: megi said we might need to tweak something in uBoot
Aug 21 18:08:11 <Herrie> Camera stuff should be in defconfig as y not as m from what I understood
Aug 21 18:09:10 <Tofe> let me the backlog in that channel
Aug 21 18:10:10 <Tofe> ah, I don't have it, maybe it was elsewhere
Aug 21 18:10:48 <Tofe> Herrie: so the issue is common to many people?
Aug 21 18:11:35 <Herrie> Tofe: Pinephone Telegram channel
Aug 21 18:11:54 <Tofe> ah ok, I didn't follow there for a while
Aug 21 18:12:38 <Herrie> Ah wait "pine64 dev" one acutally
Aug 21 18:12:39 <Herrie> IIRC, 1 << GRF_IO_VSEL_BT565_SHIFT => 0x3 or find the proper macros
Aug 21 18:13:02 <Herrie> https://github.com/Herrie82/u-boot/commit/88889fa2f17be49066e8c0c4cda3cbd0cdfa96db#diff-d34f33744571e61a2d3ba5f37fc6a3202070689fb1986d488a4358475014381bR28
Aug 21 18:28:33 <Tofe> but we do already have that commit, is there something to change here?
Aug 21 18:32:50 <Herrie> To change that value megi said
Aug 21 18:33:06 <Herrie>  1 << GRF_IO_VSEL_BT565_SHIFT into  1 << GRF_IO_VSEL_BT565_SHIFT => 0x3 
Aug 21 18:33:15 <Herrie> But I'm not sure how or what exactly
Aug 21 18:33:20 <Herrie> Anyway 5.17.9 kernel boots for now
Aug 21 18:33:23 <Herrie> Just newer not
Aug 21 18:33:32 <Herrie> Logs are OK, just display doesn't turn on
Aug 21 18:33:41 <Herrie> I think it's strange it's connected to camera but well
Aug 21 18:34:16 <Tofe> I guess the new line should be "rk_setreg(&grf->io_vsel, 0x3);"
Aug 21 18:34:47 <Herrie> megi said: <megi1> set io voltage for gpio3d/4a to 1.8v
Aug 21 18:34:58 <Herrie> And these were the instruction, I couldn't make much out of it
Aug 21 18:36:41 <Tofe> well maybe looking at the dts would help, but I'm fine trying the new line blindly :)
Aug 21 18:38:15 <Tofe> I'll see if I can find the gpio in the dts
Aug 21 18:38:25 <Tofe> just to understand
Aug 21 18:39:53 <Herrie> This is where cameras are added: https://github.com/megous/linux/commit/09b6631085dece35363afff3d60186a18c61be57
Aug 21 18:42:57 <Tofe> ok, well, I'm still not playing in the same league as megi :P
Aug 21 18:53:58 <Herrie> Tofe: same here
Aug 21 19:03:03 <Herrie> I asked megi to clarify
Aug 21 19:06:28 <Herrie> I tried rebasing uBoot but got stuck again.. Need to check the logs, it's busy with do_configure forever and the log grows to GB's of size. I had this before, but forgot how to fix it
Aug 21 19:06:31 <Herrie> WIll check some logs
Aug 21 19:12:11 <Herrie> Ah OK found what it might be
Aug 21 19:12:19 <Herrie> Seems need to add some defconfig values for uBoot
Aug 21 19:22:32 <Herrie> 1 fixed, another one testing now
Aug 21 20:29:18 <Herrie> OK uBoot master now builds after a few tweaks... Question is of course if it boots ;)
Aug 21 20:29:22 <Herrie> That I'll know soon
Aug 21 20:43:00 <Herrie> Seems it doesn't boot and also no serial, so not much help :P
Aug 21 22:28:20 <Herrie> Tofe: Seems megi meant this: https://github.com/Herrie82/u-boot/commit/0d2863a07d9b4e4842e9d7ef5aea04c31f04da34
Aug 21 22:28:25 <Herrie> Will test it in the morning
Aug 21 22:28:53 <Tofe> ok, as I thought then
