- By fully describing the pcie hardware for the RTL8125s (rtl8169) present on the
board, we get to alias them to ethernet0/1. In return, (mainline) u-boot will by
default patch the runtime FDT though it's fdt_fixup_ethernet() implementation,
hopefully resulting in fully stable MAC addresses without the need to program
the RTL NIC's EEPROM; as an added benefit, u-boot MAC & kernel MAC would match,
facilitating network-boot setups.
Problem:
On Helios64 boot, the Type-C PHY (ff7c0000.phy) gets stuck in
"deferred probe" state with unknown reason. This causes:
- USB 3.0 SuperSpeed via Type-C port not working
- DisplayPort via Type-C (Alt Mode) not working
The following messages appear in dmesg:
platform ff7c0000.phy: deferred probe pending: (reason unknown)
platform fe800000.usb: deferred probe pending: wait for supplier /phy@ff7c0000/usb3-port
platform fec00000.dp: deferred probe pending: wait for supplier /phy@ff7c0000/dp-port
Along with dependency cycle warnings:
/phy@ff7c0000/dp-port: Fixed dependency cycle(s) with /i2c@ff3d0000/typec-portc@22/connector
Root cause:
The Helios64 DTS uses a legacy Type-C connection method:
&tcphy0 {
extcon = <&fusb0>; // Expects extcon from fusb302
};
However:
1. The FUSB302 driver with TCPM support (since kernel ~4.14) does NOT
create extcon devices
2. Instead, it uses the Type-C connector class (/sys/class/typec/)
3. The phy-rockchip-typec driver calls extcon_get_edev_by_phandle(),
fails to find an extcon device at the specified phandle, and
returns -EPROBE_DEFER
4. The PHY remains in deferred probe indefinitely
The extcon-cables property is present in the DTS, but without a
typec_extcon_bridge node it serves no purpose.
This bug has existed since Type-C support was added to Helios64
(at least since kernel 6.6). It likely worked with older fusb302
driver versions, but broke after the transition to TCPM.
Solution:
Use the typec-extcon-bridge driver (Armbian patch from Ondrej Jirman/megi)
which translates Type-C connector class events to the extcon interface.
The Pinebook Pro patch (board-pbp-add-dp-alt-mode.patch) implements this
correctly: it has a typec_extcon_bridge node, and all extcon references
point to it rather than directly to fusb0.
Changes:
1. Add typec_extcon_bridge node with compatible = "linux,typec-extcon-bridge"
2. Change extcon = <&fusb0> to extcon = <&typec_extcon_bridge> in
tcphy0, cdn_dp, u2phy0, usbdrd_dwc3_0 nodes
3. Add usb-role-switch, mode-switch, orientation-switch properties
to fusb0 connector for integration with the bridge
4. Update PDO definitions with DUAL_ROLE and DATA_SWAP flags
5. Convert typec-altmodes property to modern altmodes subnode format
(required for TCPM port registration)
6. Add extcon,ignore-usb to u2phy0 (following Pinebook Pro pattern)
7. Add snps,usb3-phy-reset-quirk to usbdrd_dwc3_0
After this fix:
- Type-C PHY (ff7c0000.phy) no longer stuck in deferred probe
- USB 3.0 SuperSpeed via Type-C port should work
- DisplayPort via Type-C (Alt Mode) should work
- Correct cable orientation detection
- USB role switching (host/device)
Known remaining issues:
- FUSB302 fails to register TCPM port with error:
4-0022 typec_fusb302: cannot register tcpm port
This prevents USB Power Delivery negotiation. The root cause
appears to be in the connector configuration and requires
further investigation.
- move patches into version folder (`atf-rockchip` -> `atf-rockchip/v2.13`)
- also prepares patches for v2.14 since I had them anyway
- keeps using v2.13 for now, someone can test v2.14 later and bump; I've no rk3399
- new patches:
- add `-no-pie` to rk3399's m0 build LDFLAGS (since upstream doesn't honor M0_LDFLAGS)
- bump PMSURAM_RSIZE from 8k to 16k to avoid overflows - confirmed working by Amazingfate
- build tested OK on jammy/bookworm/trixie/noble/resolute
- resolute's gcc 15 and it still builds
- now each arch has its own dt folder, with its own Makefile auto-patched
- simple Makefile autopatching with `add-only: true`
- as example convert 01 null-patch to bare-dt in `dt_32/` (drop from series too)
- this patches u-boot default addresses with the same values used in the boot-genio bootscript
- this enables booting extlinux with large kernels and initrd (eg: `EXT=u-boot-menu`)
- backport fixes from upstream u-boot for
- BTRFS (plus enable BTRFS and BZIP2 support for radxa-nio-12l)
- tested with `CARD_DEVICE=/dev/mmcblk1 ROOTFS_TYPE=btrfs BTRFS_COMPRESSION=zstd` (no UFS!)
- also with `EXT=ufs CARD_DEVICE=/dev/sdc ROOTFS_TYPE=btrfs BTRFS_COMPRESSION=zstd` (UFS!)
- 4k block size UFS for UMS: fixes block size issue (USB issues unhandled)
- Enable "bind" command for the Mediatek-standard USB Gadget Ethernet
- this way, one doesn't need to cripple UFS to be able to boot from SD
- USB didn't get the same treatment as it's slow and **not working**...
- ...and beyond me to fix; both OTG and Host mode are funky in u-boot...
- ...but seem to work fine in kernel
- IMPORTANT: keep in mind: "SDcard is NOT UFS (4k block)" and don't fall for traps!
- Network note:
- `setenv ethaddr xx:xx:xx:xx:xx:xx` & `saveenv` & `reset`
- required for network booting; mtk doesn't use random/cpu# MAC
- required for stable MAC in kernel (keep IP from changing, etc)
- Use TFA + libdram to obtain and set the actual memory size.
- Overwrite the memory size in the devicetree that is passed to the kernel with the actual size detected.
- All credit to Bartosz Bilas' work for the mt8188/mt8370.
- This doesn't really "use" TF-A/libdram though, those call bl33 with magic arguments which we read here.
- That is implemented by a patch in TF-A for the mt8195 platform.
- With this, bl2 will pass down the DRAM size it gets from libdram
down to bl33 (u-boot proper) via a magic location
- This is a rework of the implementation for another MTK plat (GRINN)
- small hack to get around stupid "From xx" parsing in Armbian patcher
- also: fix attribution in `0023-watchdog-mtk_wdt-Correct-maximum-timeout-from-15-to`
- Switched to the binman-atf-mainline scenario with the same rkbin DDR blob
rk3399_ddr_933MHz_v1.25.bin (TPL blob, as in the old working loader). DRAM init is correct, full
4 GB visible, Linux boots.
- U-Boot and DTS updated to v2026.01-rc5. Added MDIO/PHY node and phy-handle in rk3399-kobol-
helios64.dts, fixing “mdio node is missing”. Disabled i2s2 in the U-Boot DT to avoid rockchip-
i2s ... Could not register PCM.
- boot_targets in U-Boot config shortened (mmc1, scsi0, usb0, pxe, dhcp) to avoid env_buf ... too
small; however, the last built binary still shows the warning (needs rebuild with the shortened
list or enlarging the buffer).
- Boot flow: bootstd scans SD (mmc0) and eMMC (mmc1); SD boot works even without mmc0 in
boot_targets.
- Other changes: defconfig has CONFIG_ROCKCHIP_EXTERNAL_TPL=y to use the external DDR blob.
Boots.
- this prepares everything for the more boards in the family
- which will need `dt/` folder to avoid null-patches
- label & make LEDs useful
- alias mmc0/mmc1 so they match u-boot
- expose i2c3 which is exposed in the 40-pin 27:SCL3 28:SDA3 (blue pins)
- shows up at i2c1 to userspace; why would Collabora alias an undescribed bus?
- fix bootorder (SD -> NVMe -> eMMC); USB disabled as nonworking with mainline still
- use the DT from rockchip64-6.18 so a single source for both u-boot and kernel
- note: the first (and only) RTL8169 used by u-boot is the port closest to board edge
- For 6.18 + 6.19
- mixtile-blade3: add 4-pin header fan at 40c
- mixtile-blade3: add gpu nodes
- mixtile-blade3: add vcc5v0-host-en "usb" pinctrl
- somehow results in 2 working RTL8169's behind the ASM1182e on pcie2x1l0
- which just means the _schematics lie_
- mixtile-blade3: drop rst pinctrl from pcie2x1l0 and pcie2x1l1
- this is me probably being stupid, but also required for working ASM1182e/RTL8169
- Status of this mainline port:
- Initially started by Joshua Riek (2023?)
- I then added some PCIe3x4 stuff, but never got around to finishing it
- Specifically, the 2 FUSB302's are beyond me for now
- One of them _powers_ the board. To use with mainline, power the board some other way with 12V, otherwise kaboom.
- See sre's talk on this issue; Blade3 should be similar to Rock-5b in this aspect.
- A challenge has been the PCI2x1 lanes to the miniPCIe and ASM1182e switch
- Which by themselves seem to work, but the devices behind them (Switch + RTL8169 NICs) do not get powered
- Until one day I tried to describe a (in theory) USB-related power pin, and suddenly both PCIe NICs started working!
- All that said, the board is really not stable with this; end-users are much better off with vendor kernel for now.
- Any and all help is appreciated. Those boards are nice, they've 2 FUSB302, and fancy PCIe Endpoint mode stuff.
- Schematics we have access to are in https://damwold5pt25n.cloudfront.net/blade3/file/Schematic_Blade_3_v1.1.0.pdf
- Those clearly lie.

- edge:
- kernel: taken from jriek's 6.11 wip branch
- u-boot: generic (can only boot SD/eMMC)
- straight-ish from vendor (which is a complete mess)
- front:
- blue ports work (in usb2.0 mode, which also happens in vendor kernel)
- black ports do NOT work (but are powered...?)
- back:
- white ports work in usb 2.0 mode (as expected, also in vendor kernel)
- those ports have too-long wires (flat cable) and reset all the time
- in summary: blue "USB3" ports at the front work in USB2.0 mode
- rest doesn't
- works: PCIe/NVMe, GMAC, Realtek DSA switch, SD, SPI-NOR
- does not work: USB (I didn't manage to pick correctly; lets wait for Kwiboo on this)
- untested: everything else
- the gmac works, but is connected to switch chip that is not supported by u-boot
- here I disable gmac1 for the u-boot DT
- that allows for easier booting from USB ethernet adapters
