In fact, there is not SATA issue, it is a PCI problem. Last LEDE 19.07.0 is not up pci bus at all. Not works mini-pcie port, sata controller and onboard wlan, but switch and usb works perfect.
All PCI patches already applyed, but kernel not see any pci-e controllers. Somebody know what to do with it?
which kernel,which patches? Have you added all options to config?
You can compare code,dts and config with my repo to find whats missing
Btw. Internal wifi is not easy to get into openwrt due size and backported Patches of openwrt
Try to use master branch with kernel 4.19 instead. It has some patches which not exist in 19.07 stable branch, thanks.
What options are needed?
What im do:
kernel_menuconfig -
bootargs ‘earlyprintk console=ttyS0,115200 block2mtd.block2mtd=/dev/mmcblk1,65536,RootFs,5 mtdparts=RootFs:512k(mbr)ro,512k(uboot)ro,512k(config)ro,512k(factory)ro,32M(kernel),32M(recovery),1024M(rootfs),2048M(usrdata),-(bmtpool) rootfstype=squashfs,jffs2’
and enable overriding uboot’s bootarg.
menuconfig - add block2mtd and several ata, scsi, usb and iwlwifi packages.
Again…which kernel do you use…i see only defconfig for 4.14
Here is tphy and pcie_mediatek set…but if you use 4.19 i guess it’s not
And you need to compare dts in your sourcetree with mine regarding pcie/sata
So look in your kernelconfig if these are set:
CONFIG_PHY_MTK_TPHY
CONFIG_PCIE_MEDIATEK
For sata additional these (not found in openwrt config)
CONFIG_ATA=y
CONFIG_SATA_AHCI=y
CONFIG_AHCI_MTK=mKernel 4.14.162 Tomorrow i will compare kernelconfig files.
I meant master branch with kernel 4.19 not 4.14 because related patches are in patches-4.19 folder, thanks.
Afair in 4.14 the pcie dts nodes were missing…but it looks they are added with patch.
But they are disabled…and i don’t see patch/dts enabling them…
Are you mean status = "disabled"; in the code? What if i comment out that lines or change it to ‘enabled’?
Right,but they have to “okay”. You can test in running system too
[07:58] frank@bpi-r2-e:~$ cat /sys/firmware/devicetree/base/pcie-*/status
okayokayokay[07:58] frank@bpi-r2-e:~$
But maybe you need pinctrl too…
Seems that sata has no additional dts definition…it uses one of the pcie with an pcie2sata converter
I have 3 dts files on different places. Witch one i must edit with ‘status=‘okay’’ openwrt/build_dir/host/u-boot-2019.07/arch/arm/dts openwrt/build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_mt7623/linux-4.14.167/arch/arm/boot/dts openwrt/build_dir/toolchain-arm_cortex-a7+neon-vfpv4_gcc-8.3.0_musl_eabi/linux-4.14.167/arch/arm/boot/dts
mt7623n-bananapi-bpi-r2.dts (3.9 КБ) mt7623n-bananapi-bpi-r2-1.dts (10.3 КБ) mt7623n-bananapi-bpi-r2-2.dts (9.7 КБ) In all there my files no pci sections!
Also i have 3 files in different places with name ‘mt7623.dtsi’ and in all that files disabled pci sections present. May be i must edit that files instead of mt.7623n-bananapi-bpi-r2.dts files?
the first one is for uboot…there i think you don’t need pcie atm.
i see no difference in last 2 dts…but i guess you need to add the pcie-section like in my dts
&pcie {
pinctrl-names = "default";
pinctrl-0 = <&pcie_default>;
status = "okay";
pcie@0,0 {
status = "okay";
};
pcie@1,0 {
status = "okay";
};
};
and this in the &pio {} section:
pcie_default: pcie_pin_default {
pins_cmd_dat {
pinmux = <MT7623_PIN_208_AUD_EXT_CK1_FUNC_PCIE0_PERST_N>,
<MT7623_PIN_209_AUD_EXT_CK2_FUNC_PCIE1_PERST_N>;
bias-disable;
};
};
like it’s done here

strange because i see no info that pcie is already probed…have you had any compiletime warnings/infos?
Nothing. Now i try rm-rf openwrt dir, gitclone again and start from beginning. What i must check in kernel_menuconfig?
i posted options here: ็็How to build OpenWrt 18 with SATA support for BPI-R2
but a dts-change alone should not stall cpu…i see no fix in driver in my 4.14 branch so it should be ok…maybe backporting of openwrt breaks pcie-driver…you can download drivers/pci/host/pcie-mediatek.* from my repo and compare with yours
