New mbed platform VK_RZ_A1H

[mbedNoobNinja]

These are the sources for development kit VK-RZ/A1H V4.0

• default NET tests don't pass when compiled with GCC_ARM toolchain, because there is some issue with function rtos_idle_loop(), although it physically exist in rtos library and more specifically in file rtos_idle.c. However If you specify "-Wl,--unresolved-symbols=ignore-in-object-files" flag in the link command in gcc.py, they pass.
• CAN loopback & analog pot tests may don't pass at first time (especially if they are tested along with other tests), but they always pass if they are tested alone.
• None of the export scripts are ready yet, because of too rookie python scripting skills and limited toolchain's projects template knowledge. Let the more knowledgeable people feel free to write them

You just need to add a target definition : https://github.com/project-generator/project_generator_definitions/ (find there targets.py). RZ_A1H mcu is already supported for IAR.

@TomoYamanaka Have you had any problems with GCC ARM and net libraries?

[mbedNoobNinja]

If the sources are built and linked as they are (without modification) GCC linker is not happy & complains:

C:\Projects\kitVKRZA1H\sw\mbedmicro\SDK\build\rtos\TARGET_VK_RZ_A1H\TOOLCHAIN_GCC_ARM\librtx.a(RTX_Conf_CA.o): In function os_idle_demon': RTX_Conf_CA.c:(.text.os_idle_demon+0x0): undefined reference tortos_idle_loop'
collect2.exe: error: ld returned 1 exit status
[16:15:32] Error: There were errors while building project NET_1

but if you modify the line in gcc.py to look like this, linker is OK

self.ld = [join(tool_path, "arm-none-eabi-gcc"), "-Wl,--gc-sections", "-Wl,--wrap,main", "-Wl,--unresolved-symbols=ignore-in-object-files"] + self.cpu

with_modified_gcc_py.txt, with_untuched_gcc_py.txt

I don't know who should provide this rtos_idle_loop() function and why the other toolchains haven't
this problem ?

Hi

default NET tests don't pass when compiled with GCC_ARM toolchain, because there is some
issue with function rtos_idle_loop(), although it physically exist in rtos library and more specifically
in file rtos_idle.c. However If you specify "-Wl,--unresolved-symbols=ignore-in-object-files" flag in
the link command in gcc.py, they pass.

@TomoYamanaka Have you had any problems with GCC ARM and net libraries?

The same phenomenon (default NET tests don't pass when compiled with GCC_ARM toolchain) has occurred here.
When we tested in the past, there was no problem.
It might be the following change is affecting.
#1597
It seems rtos_idle_loop() has been added in this pull request.
We tried in the LPC1768, but the same phenomenon has occurred.

Regars,
Yamanaka

Thanks guys for providing more info. Neil already replied to that PR introducing idle loop, will be fixed. Apart from this, @mbedNoobNinja can you share the test results here? (run singletest.py - the basic tests)

Ok here they are:

Thanks for sharing the tests results.

@mbedNoobNinja I locally resolved the conflicts, but can't merge it because we need CLA.

Can you please sign https://developer.mbed.org/contributor_agreement/, and share your nick on mbed.org. Thanks

[mbedNoobNinja]

Ok. The agreement in question has been signed by the name of tvendov and this form has been filled. The 10 hardware samples will be shipped soon (may be next week, I hope). That's for now. Thanks for the help.

@0xc0170 @mbedNoobNinja boards received at ARM and test results confirmed

Thanks

@mbedNoobNinja Can you please rebase your branch?

[mbedNoobNinja]

Ok branch is rebased
