SDKs for 19.3

[peteru]

Updated SDKs based on 19.3 20211010 firmware are now available for download. The T4 SDK can also be used to build code for T2 and T3.

The SDK requires a modern 64-bit Linux distribution and is provided as an install script. The installer will perform the correct relocation of the SDK to your installation directory. Please be aware that you can not simply move the installed SDK to a new place. You also can not use soft links to alias the SDK. Doing either will break things in subtle and unsubtle ways.

You will need to source the environment script to set up your shell environment for the SDK. For example, if you installed the V2 SDK in the default location:

Code: Select all

source /opt/beyonwiz/beyonwizv2/19.3/environment-setup-cortexa15hf-neon-vfpv4-oe-linux-gnueabi

Download links:

• V2 - beyonwizv2-x86_64-cortexa15hf-neon-vfpv4-toolchain-19.3.20211010.sh
• U4 - beyonwizu4-x86_64-cortexa15hf-neon-vfpv4-toolchain-19.3.20211010.sh
• T4 - beyonwizt4-x86_64-mips32el-toolchain-19.3.20211010.sh

Can the old ones be removed with a simple rm -rf /opt/beyonwiz/beyonwizt4/17.5 /opt/beyonwiz/beyonwizv2/19.3?

Your sample source line is for the old SDK.

I now have a newer Intel Mac laptop, and I may not need to have some of the build flags suppressed in the SDK.

This is what /proc/cpuinfo reports for flags & bugs:

Code: Select all

That's what I've always done.

Okay, thanks.

That should be fine. The SDKs are self contained full releases and are independent of each other. They should not be installing anything outside their own tree (/opt/beyonwiz by default), so there is no need for an uninstall script.

If you configured your project using a specific SDK, the generated Makefiles will point to that SDK. The normal practice is to have separate build trees configured for each target/SDK combination. While replacing an older 19.3 SDK with this updated one should not present problems, you might as well re-run configure after the update to ensure integrity.

Your sample source line is for the old SDK.

Thanks. Fixed.

Just tested it out and it looks like all SDKs build under Ubuntu on WSL too. Nice stuff

This is the first time I have been able to make the T and U series!
