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

Device assignment

Device assignment:
mmcdev 0 = eMMC
mmcdev 1 = SD Card

Yocto specific command Update eMMC

1. Run the following commands in the Uboot shell to create update script:

 
setenv root_loop 'setenv start 24000 && setenv r1 $rootblks16 && while itest $r1 -gt 0; do if itest $r1 -gt 0x100000; then setenv count 0x100000; else setenv count $r1; fi && mmc dev 1 && mmc read $loadaddr $start $count && mmc dev 0 && mmc write $loadaddr $start $count && setexpr start $start + $count && setexpr r1 $r1 - $count; done; setenv r1; setenv start; setenv count'

 
setenv  install_firmware 'echo MBR... && mmc dev 1 && mmc read $loadaddr 0 1 && mmc dev 0 && mmc write $loadaddr 0 1 && echo U-Boot... && mmc dev 1 && mmc read $loadaddr 3F 1FC0 && mmc dev 0 && mmc write $loadaddr 3F 1FC0 && echo U-Boot environment... && mmc dev 1 && mmc read $loadaddr 2000 2000 && mmc dev 0 && mmc write $loadaddr 2000 2000 && echo Firmware Partition... && mmc dev 1 && mmc read $loadaddr 4000 20000 && mmc dev 0 && mmc write $loadaddr 4000 20000  && echo Root FS... && run root_loop'

create the environment variable rootblks16 and set the value accordingly to the size of the RootFS in this case 2070MB.

To calculate the value of rootblks16 devide the size of the image in byte by 512 and convert the result into a hex value.

2070 * 1024 * 1024 = 2170552320
2170552320 / 512 = 4239360
4239360 = 40B000_HEX

setenv rootblks16 0x40B000
