Openwrt 19.07.3 build -- patch failure

[Nirvana]

Hello,

I try to follow your instructions on github https://github.com/Vonger/vocore2 but I get the following errors:

Code: Select all

$ patch -p1 < ./package/vocore2/openwrt.1907/vocore2-fixmaster-es8388.patch
patching file target/linux/ramips/modules.mk
patching file target/linux/ramips/dts/VOCORE2.dtsi
Hunk #2 succeeded at 36 (offset -1 lines).
patching file target/linux/ramips/dts/VOCORE2.dts
patch: **** malformed patch at line 105:  &spi0 {


and also this:

Code: Select all

$ cp ./package/vocore2/openwrt.1907/0810-es8388-support.patch ./target/linux/ramips/patches-4.14
cp: cannot stat './package/vocore2/openwrt.1907/0810-es8388-support.patch': No such file or directory


What do you recommend?

I was able to fix the first error. The patch file needs to be fixed.

Change the line

Code: Select all

@@ -16,6 +16,45 @@

to

Code: Select all

@@ -16,6 +16,46 @@

Then the patch will apply properly.

I do not know how to fix the missing file though!

Here is also another build warning that might need to be fixed?

Code: Select all

WARNING: Makefile 'package/vocore2/utils/qt5/Makefile' has a build dependency on '+libstdcpp', which does not exist

Here is another bug I found.

In your MT7628 I2C patch you are looking for the compatibility string:

Code: Select all

.compatible = "mediatek,mt7621-i2c"

But in the VOCORE2.dts file, it says

Code: Select all

compatible = "mediatek,i2c-mt7628";

So the module does not load properly

Currently ES8388 driver can not work correctly in OpenWrt 19.07.3 even with correct patch, I am fixing this so that might cause the patch broken. Please do not use that patch for now, if you need to use sound card, better to use openwrt 18.06.5 version.

Looks like 19.07.3 some drivers are changed cause es8388 can not work well.

about mediatek,mt7628-i2c, I think that issue is because that es8388 patch.

Hello,

I am trying out my vocore again... I see you have updated your build instructions on github a little but not much. Maybe they could get updated again? I see still instructions for using file "0810-es8388-support.patch" that does not exist.

But the real reason I am here, i am trying to use SD Card. It works with your firmware for Vocore 2 Ultimate, 20200812.19073.bin. But when I follow your instructions to build the firmware and make my own, I do not get a /dev/mmcblk0 device. Perhaps there is something missing from the instructions on github?

[Vonger]

Hi, do you patch the SD card driver?
It needs to patch to make sd card because default driver has a bug that it can not work with no card-detect pin device.
Most of my patches are for new function that openwrt do not allow to merge, and you can ignore them if you do not use them, like es8388 for sound.

[Nirvana]

Yes, I did:

Code: Select all

patch -p1 < ./package/vocore2/openwrt.1907/vocore2-fixmaster-sdcard.patch

The patch applied properly but when I boot the system it does not give me any device. That is why I wondered if maybe the instructions on github need to be updated, as I followed them exactly and do not get the same features as in your official firmware download.

Also, 19.07.4 is out now and I think your 1T1R/2T2R change has been added? Is that true? that is another patch that we don't need to apply?

But really what I want now is the SD card. Is there another patch I need to do besides the one mentioned above? Or is there an option I need to change in "make menuconfig" to enable SD card? I used your .config from the openwrt.1907 folder.

Thank you

[Vonger]

Do you select SD card driver?

Kernel modules => Other modules => kmod-sdhci-mt7620

OpenWrt 19.07.4 is Sep.23, maybe already fix, let me try
