Arbian Buster/Focal Loads for Macchiatobin does not enumerate PCIe correctly

[BearWood]

I was initially overjoyed to find these loads for the Macchiatobin, as they allowed me to install a boatload of software including drivers for a PCIe device.

 

Unfortunately. it appears that the U-Boot version (21.01) does not enumerate the PCIe bus correctly.  As a result, I can't test that PCIe device.

 

The relevant failure is:

 

PCIE-0: Link up (Gen2-x2, Bus0)
PCI: Failed autoconfig bar 10
PCI: Failed autoconfig bar 14
PCI: Failed autoconfig bar 10
PCI: Failed autoconfig bar 14

 

pci command output is:

=> pci 0

BusDevFun  VendorId   DeviceId   Device Class       Sub-Class
_____________________________________________________________
00.00.00   0x11ab     0x0110     Bridge device           0x04

I am able to boot the original SolidRun Macchiato load with U-Boot 15/17.01.

 

Being a noob to this aspect of Linux technology, I'd appreciate some advice on how I should approach resolving this issue.

 

Cheers,

Macchiatobin is community target - no developer close to Armbian has this hardware or does something about. This is all we have: https://github.com/armbian/build/pull/1416 - try to ping the one https://github.com/jwzawadzki that submitted board configuration. Personally I don't pay attention to this board and don't know how things were progressed since.

My 2c.

Thanks, I will try to ping jwzawadzki, though it looks like they've gone silent.
