Part Number: TDA2EXEVM
Other Parts Discussed in Thread: DRA722
Tool/software: Linux
Hi Expert,
I used VisionSDK_V2.9 on TDA2Ex echo evm, System response：
With the following modify(orange arrow) can be started：
VISION_SDK_02_09_00_00/ti_components/os_tools/linux/u-boot/u-boot/arch/arm/cpu/armv7/omap-common
But to get the USB device it failed：
root@dra7xx-evm:~# lsusb
unable to initialize libusb: -99
root@dra7xx-evm:~# dmesg | grep -i usb

Also try to update Filesystem tarballs (GLSDK 7_03_00_03), But did not solve.
Why 'DPLL locking failed for 4a008180' occurs? How to solve?
