should try debugging the Cubieboard4 at the same time
<vagrantc>
i guess the board layout is actually different between the orangepi plus2 and the orangepi plus?
<wens>
iirc the "u-boot" key forces boot from mmc0, and if it fails it find a valid bootloader, it drops to fel
<wens>
otherwise it boots from whatever the board is designed to boot from, and it's the onboard bootloader's job to check if mmc0 has a valid bootloader or not

As per wiki it's sw3 for orange pi plus.

I'm not aware about orange pi plus 2!

according to the wiki it's between the sata and hdmi ... there are no buttons anwhere near either of those ports...

wow, they moved almost everything

they did manage to put the H3 chip on straight on the plus2, at least. :)

nothing

tried sw2 and sw4 for good measure ... nothing

the SD breakout support was a little bit broken, but I made it work and documented it

as uart0_pins_a is defined in sun8i-a23-a33.dtsi

Oh no

I've never experienced a mainline guy with dts!!!

as you get the serial console messages from the SPL, your hardware hardware setup is fine
<ssvb>
just start hacking it until you get the serial console working in the main U-Boot binary and in the linux kernel

then submit the needed patches and update the wiki

<sunxi_fan>
mripard: i'm trying the setup of the simple-audio-card driving the dai0 I2S module, but i have an issue on the DTS code snippet, what could i put in the "simple-audio-card,codec" node? is there a "dummy codec" kind of declaration?
<mripard>
it wouldn't make any sense
<mripard>
in order to do something meaningful with it, you need to have a codec on your system
<mripard>
i2s is a digital bus, you need your codec to have some analog output
<sunxi_fan>
let me explain better, as i wanted just test audio out, with only three pins: LRCLK BITCLK and SDOUT, and see signals with my logic analyzer, i supposed i could setup a "dummy codec" as i don't need to configure anything..
<mripard>
hmmm
<mripard>
I don't know
<sunxi_fan>
in my previous tests, i used to setup the external codec for UDA1380, but i had to hack it a bit, because it was to be configured on I2C and so i didn't want to add this mess too.
mzki has quit [Quit: leaving]
<sunxi_fan>
i supposed you did test the I2S someway with a sample DTS cfg but i didn't find it on a lookup of the sun*dts list
<sunxi_fan>
did you use a I2S codec without a cfg?
<sunxi_fan>
i have indeed a spare I2S codec (DAC only) based on PCM5102, i surely could use it, but i'm wondering how to "declare" it correctly on the DTS, when i used the UDA1380 i defined it inside the i2c1 bus, as in:
<sunxi_fan>
it has only LRCLK, BITCLK and DATA.. so it doesn't need a I2C entry..
<sunxi_fan>
i'll have a look at it tomorrow, thanx
