Compiler/AM3352: Using latest gcc toolchain

FFatima

Part Number: AM3352

Tool/software: TI C/C++ Compiler

Hi,

We are interested in changing to the latest compiler and library versions. Currently we use (Linaro GCC 5.3-2016.02). Below are some questions. Could you please help answer:

Do we have to use only the recommended version of the compiler & LIBC versions that come along with the SDK? We are interested in moving as close to latest release of GCC, for security purposes as well as hardware support for the processor’s built in memory breakpoint technology.
Could you help us know what restrictions if any would be imposed by the kernel (something like - we need to configure toolchain with some specific options as required by Linux kernel to run on AM3352)?
Will there be any support issue in case we report issues with the drivers/kernel after using the cross compiler toolchain generated by us?

Regards,

Fariya

Hi Fariya,

To clarify, do you use Processor SDK Linux package? Which release do you currently use?

Will you use the latest version of GCC/toolchain to recompile just your application or the entire kerne/rootfs?

Hi Bin,

Currently we do not use Linux SDK. We use Arago Linux. Linux kernel is 4.9.31.

I will come back on this with more clarity, but for now you could assume, we intend to use the latest version of GCC toolchain for recompiling everything all the applications, kernel, rootfs.

Regards,

Fariya

Hi Fariya,

I think it should be okay, but I am asking it internally, and will update once I have an answer.

Hi Fariya,

It turned out that it is a bit of complicated.

If the toolchain only has minor version update, for example from gcc v9.2 to v9.2, usually it is okay (though some rare incidents happened in the past). But you could run into issues in either user space or kernel and boot loader if the toolchain major version is updated. See the example in the link below. So it is not recommended to update the toolchain with the major version changed, unless you have the expertise to handle any potential problem.
