apritzel: does allwinner's usb controller has the name? It's not dwc3?
<valdikss>
apritzel: MUSB_SUNXI?

MUSB is just the OTG controller, every SoC since the H3 has multiple standard compliant OHCI/EHCI pairs, and even for port0 they are used, for host mode
<apritzel>
I don't know if we know what the IP is exactly, but it doesn't need a special driver, the standard platform EHCI/OHCI driver works fine
<valdikss>
apritzel: I see. Just found that on rk3308 they use "Rockchip USB2.0 PHY with Innosilicon IP block driver"
<apritzel>
the PHY is separate, and apparently some Allwinner special, so maybe their own IP, or something hacked to badly that it's not recognisable anymore
<apritzel>
it's not dwc3, since that's USB 3.0, and the older SoCs only have USB 2.0. The H6 and A523 and A733 probably have something dwc3 based, but not the H616/H618

apritzel: sent a PR for sunxi-tools to add FEL support for A733, can you take a look? I've tried to collect as much more info as possible, but may not all correct, please review.. it at least works as I tested here

<apritzel>
dlan: is the 0x52000 the address that the BROM loads code from SD card to? I cannot check this, since my only A733 device is using secure boot, and in TOC0 you need to explicitly specify the load address
<dlan>
apritzel: re 0x52000, I don't what's the address that BROM loads to, so any way to find this address?
diego71 has joined #linux-sunxi
<apritzel>
I can send you a small tool that dumps it, later tonight (probably tomorrow for you)
<apritzel>
or you can hack uart0-helloworld to output the address it runs at
<dlan>
sure, it's not urgent, so fine tomorrow

dlan: can you use the vendor provided U-Boot on the Cubie A7A to run mainline kernels?
<dlan>
apritzel: haven't tried, but possibile.. where is mainline kernel for A733? did you push out somewhere?
<apritzel>
I wouldn't be aware of any code, but you can run current mainline, earlycon should give you some output at least. With a fake DTB you would get to an initrd prompt even (since the UART works)
<dlan>
ok, I got your idea
<dlan>
should be possible with uart only, with initramfs
<dlan>
I plan to get a working uboot first, kernel isn't my priority..
<dlan>
is ATF a must for running mainline kernel? or can we re-use the same ATF from A523?

<apritzel>
you can skip TF-A, but need to drop PSCI nodes from the DT, and might need to do some secure setup in U-Boot, not sure
<apritzel>
in any case you cannot just take the A523 version
<apritzel>
the kernel has the highest latency when it comes to accepting patches, and a higher scrutiny, so we should start with the kernel first
<apritzel>
plus you need the DTs accepted in the kernel first before you can use them in U-Boot
<apritzel>
I think I promised that before ;-) , but I will really try to send a pinctrl RFC in the next days

Apritzel: Hi, I received a Cubie A7A as a surprise a few days ago, along with a 32GB MMC module as a gift. I installed KDE, in case I can help with anything.
