Known Issues
Linux kernel does not start with sumo.TQMa8.BSP.SW.0005 on MBa8Xx ≤ Rev.0101
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) |
PCIe device detection
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) |
No QSPI NOR Flash support in U-Boot
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 |
