V40/R40 Boards

Subair · November 12, 2019

I have complied R40 board ( not bpi v40) with Armbian kernel and the u-boot hangs and showing BOOT. I was using u-boot 2014-07 and boot0_sdcard.fex and boot_package.fex for bootloader.

Hi everyone. I have compiled sunxi-next u-boot and activated the SoC internal analog audio codec, now I am testing the mali node. Audio Working!

Hello again, here are the system logs before, after and during the u-boot compilation

i was able to boot the board as it uses LDDR , i had to change the DRAM settings in menu config. i still have challenges to get eMMC, Ethernet working.

Hello, following the steps to add audio support to h3, v3s, a23 modified sun4i-codec to add support for r40, and if anyone else wants to try:

If you could provide this as patches for Armbian to include into the building process it would be appreciated :beer:

I did try it on my BPI M2Berry. Compile went Ok after installing the kernel-headers,

but after modprobe sun4i-codec I only got the following dmesgs:

Is there a difference for the R40/V40 CPU?
Because I think I have a "early" BPI M2Berry which hasnt the CPU which is normally on the board.

But as I did read the are compatible and differ only in work-temperatures?

JuanEsf · June 18, 2020

what happens is this is just the module, for them to work you need to add the codec node to sun8i-r40.dts and sun8i-r40-bananapi-m2-ultra.dts, just give me a few hours to fix some details and give you details how to compile u-boot with changes

JuanEsf · June 18, 2020

Compile Codec for R40/V40:

curl -s https://raw.githubusercontent.com/juanesf/codec/master/compile-codec.sh | sudo bash /dev/stdin

Compile u-boot for R40 emmc (M2-Ultra):

curl -s https://raw.githubusercontent.com/juanesf/u-boot/audio-codec/compile_u-boot_r40_emmc.sh | sudo bash /dev/stdin

Compile u-boot for R40 sd (M2-Ultra):

curl -s https://raw.githubusercontent.com/juanesf/u-boot/audio-codec/compile_u-boot_r40_sd.sh | sudo bash /dev/stdin

Compile u-boot for V40 emmc (M2-Berry):

curl -s https://raw.githubusercontent.com/juanesf/u-boot/audio-codec/compile_u-boot_v40_emmc.sh | sudo bash /dev/stdin

Compile u-boot for V40 sd (M2-Berry)

curl -s https://raw.githubusercontent.com/juanesf/u-boot/audio-codec/compile_u-boot_v40_sd.sh | sudo bash /dev/stdin

it only remains to add two lines to /etc/rc.local before exit 0:

modprobe sun8i-codec-analog

modprobe sun4i-codec

sudo nano /etc/rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

modprobe sun8i-codec-analog
modprobe sun4i-codec

exit 0

gives me a 404 - not found
Or do you need more time - because you wrote

"just give me a few hours to fix some details"?

Here is no audio-codec directory:
https://github.com/juanesf/u-boot

Do you got the part to ad to the .dts/.dtb?
I did such a ad job also for my NanoPi A64 or NanoPi Neo PCM5102A-I2S Soundboard

JuanEsf · June 18, 2020

it was only a problem with the name of the extension that has already been corrected

JuanEsf · June 19, 2020

please not use. give me more time

JuanEsf · June 25, 2020

A volunteer. What can I test and confirm if it works correctly?

should I test it with my M2Berry now?

With which kernel version should it work?

JuanEsf · June 25, 2020

yes, you can test in m2-berry, and it should work at least from kernel 5.4.x

guidol · June 25, 2020

I tested

curl -s https://raw.githubusercontent.com/juanesf/u-boot/audio-codec/compile_u-boot_v40_sd.sh | sudo bash /dev/stdin

but at the end of the script I did get

JuanEsf · June 25, 2020

you must run two commands one to compile u-boot with the codec node, the other is to compile and copy the new codec with r40/v40 support. and finally it remains to load the modules, there are two ways one is to load it manually:

sudo modprobe sun8i-codec-analog

sudo modprobe sun4i-codec

and the second way is to add the two previous commands in /etc/rc.local which loads the modules automatically. first try the manual commands, if after loading manually the sound card appears you should modify rc.local so that it loads automatically
