1. am 335x processor sdk 9.1 or 9.3 cross-compile tool

why choose to use external-toolchain-dir/arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf- instead of built-in one (just the built-in one has compilation issues ?);

For AM335x SDK 9.1 & 9.3, the toolchain is under $(TI_SDK_PATH)/external-toolchain-dir" which is the toolchain tested for TI SDK.

You may refer to "Rules.make" under the SDK installation folder, where
export CROSS_COMPILE=$(TI_SDK_PATH)/external-toolchain-dir/arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf-
Here is one e2e on the topic for your reference.

The question I have is, why can't we use the built-in arm-oe-linux instead of the external arm-none-linux ??What do I need to do if I want to use the internal arm-oe toolchain of the sdk

The external tool chain "arm-gnu-toolchain" is the tested toolchain in TI AM335x Linux SDK 9.x
Let me loop in SDK team for input on your follow-up questions.

I want to known why not use the arm-oe-linu cross compile??? if I use arm-oe what will happen?

And I also want to confirm which toolchain was used to compile the default file system in SDK 9.3

Or you could tell me which toolchain Yocoto used to compile the filesystem in SDK 9.3,external-toolchain arm-none-linux-gnueabihf-gcc or default arm-oe-linux-gnueabi-

Hi Hong, Praneeth

I had a call with customer about this question.

There is only one thing we want to check with you.

Are there any risks of using kernel compiled by external-toolchain and the filesystem compiled in Yocoto? Do they use same tool chain? Any compatibility problem？

Regards

Zekun
