+===== Known Issues =====
+==== Linux kernel does not start with sumo.TQMa8.BSP.SW.0005 on MBa8Xx ≤ Rev.0101 ====
+^ Details  ||
+^ [c]Effect[/c]  | Linux kernel does not start (no more messages after ''Starting kernel...'')  |
+^ [c]Issue[/c]  | PCIe requires external clock generator  |
+^ Affected Revisions  ||
+^ [c]Bsp[/c]  | sumo.TQMa8Xx.BSP.SW.0002\\ sumo.TQMa8.BSP.SW.0005  |
+^ [c]Module[/c]  | all revisions  |
+^ [c]Mainboard[/c]  | MBa8Xx ≤ Rev.0101  |
+^ Solution  ||
+^ [c]Fix[/c] | Upgrade to MBa8Xx Rev.0102 (please contact <support@tq-group.com> for further information)  |
+^ [c]Workaround[/c] | Use {{ :en:arm:tqma8xx:tqma8.bsp.sw.0006_dtbs-no-pcie.tar |devicetree with disabled PCIe interface}} (will be included in next BSP release)  |
+----
+==== PCIe device detection ====
+^ Details  ||
+^ [c]Effect[/c]  | Some PCIe devices (e.g. PCIe switches) may not be properly detected  |
+^ [c]Issue[/c]  | PCIe signals //clock//, //enable// and //reset// do not comply to the PCIe specification  |
+^ Affected Revisions  ||
+^ [c]Bsp[/c]  | ≤ sumo.TQMa8.BSP.SW.0005  |
+^ [c]Module[/c]  | all revisions  |
+^ [c]Mainboard[/c]  | MBa8Xx ≥ Rev.0102  |
+^ Solution  ||
+^ [c]Fix[/c] | TBD  |
+^ [c]Workaround[/c] | 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  ||
+^ [c]Effect[/c]  | Executing ''sf probe'' in U-Boot causes the first byte of the QSPI NOR Flash to be overwritten  |
+^ [c]Issue[/c]  | QSPI NOR Flash is not suppported in U-Boot  |
