Part Number: TDA2EVM5777
Other Parts Discussed in Thread: DRA742
Hi,
I am trying to "Build Linux Vision SDK for Fast Boot" with TDA2EVM5777, VisionSDK 3.07.
I am working on two documents below.
- VisionSDK_Linux_UserGuide
- Linux Boot Time Optimizations on DRA7xx Devices
So I applied QSPI boot to EVM.
And for fast booting, I saved rootfs to eMMC.
=========================================
[EVM] => ums 0 mmc 1
[HOST] => sudo rsync -av --delete ../../ti_components/os_tools/linux/targetfs/ /media/XXX/rootfs/
And change the EVM SW setting
SW2: 1110 1100
SW3: 1000 0001
SW5: 0010 1000 00
SW8: 10
========================================
After reboot, Do not mount the rootfs of the eMMC.
===================================================

If I plug in the SD card here, the rootfs in the SD card is mounted and boot.

The kernel command line is shown below.
As far as I know, mmcblk1p2 is an SD card.

---------------
I think the setting is wrong, but I don't know.
I worked just like the document.
And I have another question!
When working on QSPI-Flash on HOST, The following message comes from the target, is this an error?
"request fdf2a400 was not asked to ep1-in-bulk"

Lee.
