Suggestion for adding docker image support

[gitE0Z9]

After compiling this toolchain on colab, I feel this process is really time-consuming and not portable at all, the building directory and the install-dir are both large in size.

It would be great if you could provide docker image version to simplify this part and make installation easier.

Thanks!

@gitE0Z9 if you want something immediately usable you may try to use our pre-built toolchain, all flavors of which you may find here: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2021.03-release.

Please let us know if for some reason pre-built version doesn't work for you and we'll try to see how that might be improved.

@abrodkin Thanks for your reply, I didn't notice that there are releases already, shall give it a try later.
At the same time, my tflite micro project with the compiler arc-elf32-g++ v10.2.0 built with the git repository
showed me this message and the option -mno-sdata does't solve the problem.

In case you want to know related code:

[abrodkin]

@gitE0Z9 could you please post results of compilation with -mno-sdata?

[gitE0Z9]

@abrodkin Not sure if this is what you need. I got memory.map but output.elf failed.

I got some progress by deleting existed .o file in tensorflow, and now I faced a new file wf_exp.c.
This is compiled with pre-build release.
Would it be a problem in libm.a file or newlib link? Is it overflowed?

Here are some quick observations:

1. probably mno-sdata will not help for time being as the relocation is in a prebuild library (i.e., libm.a)
2. The error looks like you cannot fit the interrupt vector table (ivt section) to ICCM1 memory
3. Most probably your problem resides in the linker script.

@abrodkin @claziss Thanks for you guys generous help, I had found the solution finally.
It is because the source project (https://github.com/HimaxWiseEyePlus/himax_tflm) was compiled with 2020-09 release,
thereafter the compilation with 2021-03 release won't work.

@gitE0Z9 Thanks for leting us know. It seems the 2021.03 release is broken and needs to identified why. @abrodkin isn't this release when we jump to corss-ng? Can you investigate more in depth what is going on? Thanks.

[abrodkin]

@gitE0Z9 is it possible to reproduce your problem with sources available from https://github.com/HimaxWiseEyePlus/himax_tflm?
Could you please provide complete instructions on how to get it reproduce so that we may get to the root cause of that issue?
