===== Known Issues =====
===== Linux BSP Rev.0113 ======
==== U-Boot 2017.11 ====
^ U-Boot Environment ^^
^ Affects | U-Boot Environment |
^ Issue | U-Boot Environment loading/storing uses eMMC only |
^ Effect | If eMMC contains a valid environment sector the BSP Rev.0113 U-Boot will load that environment regardless of the actual boot device (e.g. sd card).\\ As the partition layout has been changed with BSP Rev.0110, boot commands from environments of BSP Revs. ≤ 0109 will not work anymore.\\ In consequence booting BSP Rev.0113 U-Boot will fail if an environment from BSP Rev. ≤ 0109 is present in eMMC. |
^ Solution / Workaround | Will be fixed in next BSP release.\\ __Workaround boot failure:__
- Boot from SD card using BSP Rev.0113 U-Boot
- Interrupt autoboot to access the U-Boot command line interface
- Set eMMC to be the active mmc device\\ **''mmc dev 0''**
- Erase the environment sector\\ **''mmc erase 0x800 0x800''**
- Reboot the system:\\ **''reset''**
- Interrupt autoboot to access the U-Boot command line interface
- Save default enviroment to eMMC\\ **''saveenv''**

===== Linux BSP Rev.0109 ======
==== PTXdist ====
^ Build failure on Ubuntu 16.x host ^^
^ Affects | Image/RootFS creation |
^ Issue | Segmentation fault caused by ''genimage-7'' tool when run on Ubuntu 16.x host |
^ Effect | Target //root.ext2// fails to build. |
^ Solution / Workaround | Use ''genimage-8'' instead of ''genimage-7''\\ \\ 1. copy ''host-genimage.in'' and ''host-genimage.make'' from ''/usr/local/lib/ptxdist-2015.05.0/rules/'' to ''TQMa6x-BSP-REV.0109/rules/''\\ 2. modify ''TQMa6x-BSP-REV.0109/rules/host-genimage.make'' like this:\\ HOST_GENIMAGE_VERSION := 8
HOST_GENIMAGE_MD5 := 506a0cd6722431af87ef7cfe437662cc3. run ''ptxdist clean host-genimage''\\ 4. run ''ptxdist images'' |
===== Linux BSP Rev.0105 ======
==== PTXdist / U-Boot ====
^ 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''|
==== iperf3 ====
^ Bug in UDP test ^^
^ Affects | iperf3 package provided with BSP |
^ Issue | iperf3 reports extremly high packet loss when performing an UDP test |
^ Effect | iperf3 is not suitable to determine meaningful UDP performance values |
^ Solution / Workaround | Use older version of iperf (e.g. iperf2) |
===== 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_TQMA6**S**_INSTALL_U_BOOT_IMX''\\ to\\ ''ifdef PTXCONF_U_BOOT_TQMA6**Q**_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). |
==== OSELAS.Toolchain 2013.12.x from debian.pengutronix.de ====
^ Qt Creator debugging fails ^^
^ Affects\\ Subject | GDB |
^ Issue | Missing support for Python scripts (i.e., gdb is not configured using ''--with-python'') |
^ Effect | Qt Creator Debugging Helpers will not work (properly) |
^ Solution / Workaround | Build toolchain from source |

* **Solution**: fixed in newer releases
===== CAN =====
* **Affected Revisions**: up to 0100
* **Issue**: wrong Bitrate setup
* **Solution**: fix planned for REV 0101
===== Ethernet =====
* **Affected Revisions**: all
* **Issue**: missing support for GIGE
* **Solution**: Software fix planned for REV 0101, needs MBa6x 0102
===== USB =====
* **Affected Revisions**: all
* **Issue**: Hub power issue, hub signals that port draws too much current even if the hub is powered
* **Solution**: fixed, needs hardware workaround on MBa6x REV0100, fixed on newer revisions
===== I2C =====
* **Affected Revisions**: prerel 20130407

====== Toolchain ======
===== OSELAS.Toolchain 2012.12.x =====
* **Affected Revisions**: all
* **Issue**: missing support for cortex-strings in glibc
* **Solution**: \\ 1) If performance impacts are noticed, use OSELAS.Toolchain for cortexa8. It is known to work \\ 2) Try other toolchain with cortex-strings support
