Details
Effect Linux kernel does not start (no more messages after Starting kernel…)
Issue PCIe requires external clock generator
Affected Revisions
Bsp sumo.TQMa8Xx.BSP.SW.0002
sumo.TQMa8.BSP.SW.0005
Module all revisions
Mainboard MBa8Xx ≤ Rev.0101
Solution
Fix Upgrade to MBa8Xx Rev.0102 (please contact TQ Support for further information)
Workaround Use devicetree with disabled PCIe interface (will be included in next BSP release)

Details
Effect Some PCIe devices (e.g. PCIe switches) may not be properly detected
Issue PCIe signals clock, enable and reset do not comply to the PCIe specification
Affected Revisions
Bsp ≤ sumo.TQMa8.BSP.SW.0005
Module all revisions
Mainboard MBa8Xx ≥ Rev.0102
Solution
Fix TBD
Workaround Limit PCIe speed to Gen1 by using proper devicetree *-pcie-gen1.dtb (provided with BSP release sumo.TQMa8.BSP.SW.0006)

Details
Effect Executing sf probe in U-Boot causes the first byte of the QSPI NOR Flash to be overwritten
Issue QSPI NOR Flash is not suppported in U-Boot
Affected Revisions
Bsp sumo.TQMa8.BSP.SW.0005
Module all revisions
Mainboard all revisions
Solution
Fix TBD
Workaround N/A
