Questions about branch meaning and toolchain compatibility.

[TUNGHUAYU]

Hi andestech,

I have an MCU with a D10 Andes processor. I want to set up the environment for development.
However, something is confusing me. Therefore, I put the three questions showing below:

1. Is ast-v3_2_3-release-v5 the toolchain for Andes architecture V5?
   and Is ast-v3_2_3-release-v3 the toolchain for Andes architecture V3?

2. If question 1 is TRUE, Could you provide the batch file for building "ast-v3_2_3-release-v3" branch?
   I want to build the branch ast-v3_2_3-release-v3 for the V3 toolchain. However, there is no batch file for building work.

3. If question 2 is FALSE, can the V5 toolchain replace with the V3 toolchain.

Thank you for your time.

Best regards,
Terry

Yes, ast-v3_2_3-release-v5 is the toolchain for Andes architecture V5 and ast-v3_2_3-release-v3 the toolchain is for Andes architecture V3. We can provide the bash script as V5 and you can build by yourself on cygwin.

Hi, shaochung,

Thank you for your reply.

In my case, I want to build the D10 development environment in Ubuntu 18.04.

I already built the V5 toolchain successfully on Ubuntu 18.04.
However, I cannot build the V3 toolchain by bash script from the V5 branch.
Therefore, could you provide the bash script for building the V3 toolchain based on Ubuntu 18.04.

p.s.
There are three packages that should be appended to the Prerequisites list.
Or it makes something wrong when building work-time.

$ apt install gcc-multilib libutil-freebsd-dev libncurses5-dev libncursesw5-dev

Thank you very much.

Best regards,
Terry
