pcie to sata board not work on firefly rk3399

[idreamerhx]

Hi,

I got a pcie (firefly m.2 ngff M-Key) to sata board. Kernel source is from this repository and archlinux arm rootfs.

I config the dts to turn on pcie 3.3v power, and I tested ok.

lspci shows: 00:00.0 PCI bridge: Fuzhou Rockchip Electronics Co., Ltd Device 0100 01:00.0 IDE interface: ASMedia Technology Inc. ASM1061 SATA IDE Controller (rev 01)

lspci -vv shows:

I don't know if I need to modify kernel source to add some more space for more than one pcie?

Thanks all.

I tried this: https://www.linuxquestions.org/questions/linux-kernel-70/kernel-fails-to-assign-memory-to-pcie-device-4175487043-print/

but not work. dmes gives the same message.

I got a i.mx6 patch from: https://community.nxp.com/thread/308436

but I'm not sure how to fix rk3399.

[alexeijd]

apologies for the possibly dumb question, but what changes did you have to make to the dts to enable power on the pci-e?

[idreamerhx]

@alexeijd Thanks for your reply. I nearly forget this problem after some days of hard work but not solved this problem. Here is my dts. https://pastebin.com/xXWZLF0y

I have test 3.3v in pcie(M.2) pin2 and pin4 ( Please refer Firefly-RK3399_V10_SCH_(2017-2-8).pdf)

[alexeijd]

Thanks for the pointers, In my case I'm getting a different output: [ 0.929421] rockchip-pcie: probe of f8000000.pcie failed with error -110 with an empty lspci output makes me think that my pcie is disabled or broken my card is getting power from the bus (it lights an led on the card fine) and I know the card (dual intel gige m.2) is working fine, and should be ok (3.3v), I just can't see anything

@alexeijd I have close to the similar problem, except my card is a Delock PCI Express Card > Mini PCIe with a Telit LM960 LTE module and the LED on my PCIe board is not lighting up. Were you able to solve your problems? How can I check if PCIe is enabled and if not change that?

My dmesg: https://pastebin.com/FHMGRgVG

FWIW, had the same -110 error with M.2 SATA card (ASM106x chipset) on NanoPC-T4 (RK3399) with 4.4.x from FriendlyARM and from Rockchip, but problem went away on mainline 5.8.5. Details here: https://discuss.96boards.org/t/pcie-link-failure-with-pcie-device-card/9643/7?u=redfish

@radfish How did you install 5.8.5 on your board?
