Known Issues

Linux BSP Rev.0105

PTXdist

U-Boot build failure
Affects	U-Boot build stage
Issue	Typo in configs/platform-tq-mba6x/rules/u-boot-spi-tqma6s.make
Effect	When U_BOOT_SPI_TQMA6S is selected, U-Boot fails to build properly.
Solution / Workaround	Change line 29 in configs/platform-tq-mba6x/rules/u-boot-spi-tqma6s.make from `U_BOOT_SPI_TQMA6S_LICENS E := GPLv2` to `U_BOOT_SPI_TQMA6S_LICENSE := GPLv2`

Linux BSP Rev.0104

PTXdist

U-Boot build failure

Affects	U-Boot build stage
Issue	Typo in configs/platform-tq-mba6x/rules/u-boot-tqma6q.make
Effect	When PTXCONF_U_BOOT_TQMA6S is not selected (i.e. U-Boot should only be build for TQMaQ), U-Boot fails to build properly.
Solution / Workaround	Change line 66 in configs/platform-tq-mba6x/rules/u-boot-tqma6q.make from `ifdef PTXCONF_U_BOOT_TQMA6S_INSTALL_U_BOOT_IMX` to `ifdef PTXCONF_U_BOOT_TQMA6Q_INSTALL_U_BOOT_IMX`

Linux Kernel 3.16

Kernel does not boot
Affects	U-Boot & U-Boot environment
Issue	New Kernel memory map
Effect	Kernel does not boot (properly) with U-Boot and U-Boot environment from BSPs < Rev. 0104
Solution / Workaround	Use U-Boot from BSP Rev. 0104 and reset U-Boot envrionment to default (any custom variables can, of course, be added again afterwards).

Qt Creator debugging fails
Affects Subject	GDB
Issue	Missing support for Python scripts (i.e., gdb is not configured using `–with-python`)
