Linaro GNU Compiler (GCC) toolchain : for Renesas RZ (ARM Cortex-A9) + FreeRTOS (Demo Project)

by Steffen Sprung

*Hi LINARO-TEAM,* I would like start a software development on a “Renesas RZ (ARM Cortex-A9) MPU (R7S721010xxx” by using Eclipse IDE (Kepler - 4.3.1). > Global objective = Use free SW development tools I have read, that the “Linaro GCC Toolchain Release Supports Full Range of ARM Cortex-A Processors” and it’s an open source software for the ARM architecture, including the GCC toolchain. > Well – I think that is what I need. So, I have installed the Linaro Toolchain (gcc-arm-none-eabi-4_7-2013q3-20130916-win32.exe) and test the compilation of the “*Hello World ARM C Project*” for the Target Processor “cortex-A9” > So, the compilation is OK. *NOW, I would like prepare a small TEST-Project with FreeRTOS.* FreeRTOSV8.0.0_Release_Candidate_2 > I have found the “Renesas RZ (ARM Cortex-A9) RTOS Demo”: http://www.freertos.org/Renesas_RZ_Cortex-A9-RTOS.html But the two projects are provided to be built with the* IAR Embedded Workbench <http://www.iar.com/ewarm>* or the *ARM DS-5 <http://arm.com/products/tools/software-tools/ds-5/index.php> embedded development tools*. > I have seen that the DS-5 Development Studio is not for free but it use also the Linaro GNU Compiler (GCC) toolchain. So, I have tried to import the “Renesas RZ (ARM Cortex-A9) RTOS Demo” project to Eclipse, *but the import doesn’t work – and I’m not sure that the project uses the Linaro GNU GCC Compiler**.* > I think that Demo project for DS-5 use also special plugins/configuration settings from the Development Studio – so this can’t work ?!… *HELP:* *I’m new in the “Eclipse IDE / Compiler (GCC) toolchain” WORLD … * So, can you help me to give me a good direction - *what I need to do *to make running this small “Blinky-Demo for Renesas RZ (ARM Cortex-A9) with the FreeRTOS” by using the Linaro GCC Toolchain. > Or have you another small Demo project for the Linaro GCC Toolchain which uses the FreeRTOS for the Renesas RZ (ARM Cortex-A9) family? … Or you think that is not easily possible to do that for a Newcomer like me? I hope that you can help me to put me on the right road.

* Libsanitizer for AArch64: (4/10) - seems to be mostly working, but trouble with validation both using the Foundation Model and qemu-aarch64. - Some tests seems to loop forever while unwinding under qemu, but run fine under the Foundation model - Conversely the Foundation Model shows some random errors, and the corresponding tests pass under qemu - Some random timeouts with the Foundation Model, despite using ssh multiplexing - Added a small patch to qemu to hande missing mmap flag. Need to send upstream. - asked Rob to run GCC testsuite with my patch on AArch64 but it's too unstable these days * Cross-validation (2/10) - script now able to validate a GCC patch and compare results with unmodified GCC trunk - added arm-none-eabi target - using qemu-aarch64 for aarch64-none-linux-gnueabi but the validations now time out. Need investigation, but I might have to revert to no execution for this target. - identified a problem with the recent armv7-ve patch * Benchmarks: (1/10) - collecting data for 4.8 tables * Peeling: (1/10) - backported new vectorizer cost model to check it if's OK to include it in our next release * Misc (2/10): conf-calls, meetings, docs (howtos for TCWG) == Next == * libsanitizer on AArch64 * fix cross-validation on aarch64-none-linux-gnu * benchmarks: complete table * backports: chek new vectorizer cost model, monthly branch merge, review Michael's backports of Crypto intrinsics

== Progress == * Investigate "PGO" for Aarch64 (3/10). Bootstap testing aarch64 with PGO for GCC.Stage 2, feedback profile in progress. Tested a small test case for -fbranch-probabilities, works same as x86_64. Working on checking the "gcda" files generated and profile runs for coremark. * Cbuild2 discussed with rob, ryan on using cbuild2 for developement. (3/10) Thanks Rob for fixing some issues and adding features that I requested. Tested some features added. Captured it as FAQ. * Reinstalled ubuntu OS on my laptop (2/10) Misc (2/10) ------------- AMD internal meetings and did some investigations == Plan == - Continue run EMBCC and coremark benchmarks with -PGO enabled. - Going on marriage vacation from 07-Feb till 06 March == Issues=== Follow up upstream libssp GCC discussions. No response yet after 2 pings :(

by Rob Savoye

== Progress == * Got binary release building working again. (2/10) * Added a node_selector to Jenkins for the new Beagle Board Blacks, and get those working for native builds. (TCWG-379, 1/10) * Fix configuration of 'build-all' project in Jenkins, now fires up cross builds for supported targets, plus native builds on Chromebooks and Beagle Board Blacks. (1/10) make networking route externally. (TCWG-380) * Meetings and Misc. (3/10) * Got TCWG build farm, all nodes offline fixed. * Wrote wiki page on the build farm. * Updated Java to 1.6 on the Beagle Board Blacks in the TCWG build farm. * Added support to specify an alternate prefix for installation. * Got QEMU and Foundation Model running on TCWG x86_64 build slaves so Jenkins can use them for native builds. (TCWG-380 - 2/10) * Got Rasberry PI softfp image running under QEMU, tried to do build. (TCWG-380 - 1/10) == Plan == * Build static gdbserver for target via Cbuildv2. * Add Win32 installer for Canadian cross built binary releases to Cbuildv2. * Get Kugan's benchmark branch running on build farm. * More Jenkins maintainance. == Potential Leave == * Still working out the huge amount of details, but strongly considering going to Mt Everest after Connect. It'd be a long and rough trip, but a once in a lifetime opportunity.
