Hi TI,
We port an AM1808 BSP from hawkboard which use linux-2.6.32-rc6. Now, we encount a problem maybe caused by an uart driver bug. My questions are:
- Does there any uart driver related bug fix from linux-2.6.32-rc6 to linux-3.1.10(found in ti-sdk-omapl138-lcdk-01.00.00.bz2)?
- If there is, could we backport the bug fix to linux-2.6.32-rc6? Because we don't want to upgrade everything to ti-sdk-omapl138-lcdk-01.00.00.bz2
- What's your suggestion about upgrading to ti-sdk-omapl138-lcdk-01.00.00.bz2?
Another problem:
The lastest OMAP-L138_FlashAndBootUtils_2_40.tar.gz still can't erase whole NAND chip. The command is:
# mono $(UBLTOOLSDIR)/OMAP-L138/GNU/sfh_OMAP-L138.exe -erase -targetType AM1808 -flashType NAND -p /dev/ttyS0
After I erase the whole chip and flash ubl + uboot. I boot the board to uboot and find uboot environment settings and kernel image are untouched.
Is it an unfixed bug or I missed something?
Thanks
