06:09 <pnill> Here's a better question, does anyone know if in the BSP u-boot 2014 has broken serial code? I saw somewhere on the wiki that some later version of u-boot mainline fixes serial for this specific chip (R40/A40i)

09:32 <pnill> So after sitting here for hours upon hours, I can confirm that based on the sys_config.fex and the data sheet that pin configurations and the "Mux" appear to be correct as far as the function of the port, but I still can't seem to get UART to function I'm wondering if there's something that's supposed to happen prior that's not like a pull on another pin or something.

09:32 <pnill> Right now I'm just recompiling fes1 from bsp spl within the u-boot setup and launching it, but not getting any serial output.

09:33 <pnill> I also don't understand how the pins translate from PB23/PB22 to what I'm seeing in the header of the binary.

09:34 <pnill> Mapping out the data to normal_gpio struct this is what I'm seeing.

09:34 <pnill> 2 makes sense I suppose if B -1 = 2

09:34 <pnill> but I don't know where 8 comes from in regards to 23

09:34 <pnill> for port_num

09:35 <pnill> mul_sel being 4 also confuses me because according to the datasheet it should be 2 to be uart0, and in the sys_config.fex it is set to 2

09:35 <pnill> pull,drv_level,data I don't know anything about.

09:36 <gamiee> pnill: so, the UART works only in kernel, not in u-boot, right ?

11:26 <apritzel> jernej: do you have any other H6 TV boxes aside from the Tanix TX6 (mini)?

11:27 <apritzel> I opened up my "T95max" and found a raw NAND flash inside (not eMMC)

11:27 <jernej> no, why?

11:27 <apritzel> I was hoping the days of raw NAND flash were gone ... :-(

11:27 <jernej> I'm actually looking where to get TX6 mini

11:28 <apritzel> the mini is the TX6 with an XR819 instead of RTL wifi?

11:29 <apritzel> my T95max at least has an XR819, so no Bluetooth

11:29 <jernej> there are several differences, you named one

11:30 <jernej> another is one USB less (but I couldn't figure which), less RAM, less eMMC storage

11:30 <jernej> but with addition of analogue audio and CVBS

11:31 <apritzel> oh, I see

11:34 <jernej> there is also Beelink GS1 (supported by mainline), but it also has eMMC

11:35 <jernej> although someone on LibreELEC forum asked how to install LE on some random H6 board (TV box?) which has nand

11:35 <jernej> so I know they exist...

16:09 <montjoie> libv: thanks

17:56 <pnill> gamiee: I don't have a kernel loaded yet, mainline u-boot UART works.

17:56 <pnill> BSP u-boot (Which I want to use due to nand) does not work.

17:57 <pnill> and the port configuration that's in the header is as above, and I tried to map it out to that "normal_gpio" structure

17:57 <pnill> but I don't think the port configuration is correct based on that despite it being correct in the sys_config.fex

17:57 <pnill> https://i.imgur.com/9aaZtAF.png

17:57 <pnill> based on data sheet it should be PB22/PB23 function/multiplex 2 for UART0

17:58 <pnill> "port" is 2 which makes sense B - 1 = 2

17:58 <pnill> but then port_num is assigned to 8

17:58 <pnill> and mul_sel seems to be 4

17:59 <pnill> https://github.com/Allwinner-Homlet/H3-BSP4.4-bootloader/blob/master/uboot_2014_sunxi_spl/sunxi_spl/fes_init/main/fes_head.c#L63

17:59 <pnill> That's what I'm looking at just decompiled it.

17:59 <pnill> https://i.imgur.com/q8jjaR9.png

17:59 <pnill> where 80BC is where the header lives based on the reference to it

18:00 <pnill> so I guess port_num should be 23/22 not 8/9

18:02 <pnill> https://github.com/linux-sunxi/sunxi-tools/blob/master/bootinfo.c#L80

18:03 <pnill> vs. Data sheet: https://media.discordapp.net/attachments/916039717240336395/916967047714443274/Screenshot_20211205-001920.jpg

18:03 <pnill> PB22/PB23 and function 2

18:04 <pnill> I guess I'm looking for an answer to two things, one.... is "8" correct instead of 22/23 or should it actually be 22/23 there in "port_num"

18:04 <pnill> and also anyone know why the sys_config.fex may get changed to 8 instead of 23/22 if it is supposed to be 22/23.
