TDA4VM: Add layer

Part Number: TDA4VM

Hi team,

SDK: Processor SDK Linux for J721e 08_06_01

The compilation is complete and burned to the SD to enter the system and the customer is currently planning to add layer. 

$ cd /ti-processor-sdk-linux-j7-evm-08_06_01_02/yocto-build

$ . ./sources/oe-core/oe-init-build-env

$ bitbake-layers create-layer meta-stressapptest

However, the problem occurs as shown in the following figure:

They then tried to modify toolchain_base_path, but because of the lack of GCC-arm-9.2-ti2020.01-armv5-x86_64-arm-none-Linux-gnueabi, the new meta-stringapptest cannot be generated. 

NOTE: Starting bitbake server...

According to doc, only 2 toolchains are required:


1) Is it possible to remove the GCC-arm-9.2-ti2020.01-armv5-x86_64-arm-none-Linux-gnueabi requirement? If so, how to modify it?

2) If not, where can they download gcc-arm-9.2-ti2020.01-armV5-x86_64-arm-none-Linux-gnueab? 

Could you help check this case? Thanks.

Best Regards,
