## Summary This PR adds support for the PINE64 StarPro64 64-bit RISC-V SBC, based on ESWIN EIC7700X SoC. Most of the code was derived from NuttX for Milk-V Duo S (SOPHGO SG2000). [The modified code is explained here](https://lupyuen.github.io/articles/starpro64#appendix-port-nuttx-to-starpro64) ### Modified Files `boards/Kconfig`: Added StarPro64 board ### New Files in boards/risc-v/eic7700x/starpro64 `src/eic7700x_appinit.c`: Startup Code `include/board.h`: StarPro64 Definitions `include/board_memorymap.h`: Memory Map `src/etc/init.d/rc.sysinit`, `rcS`: Startup Script `src/.gitignore`: Ignore the tmp filesystem `scripts/ld.script`: Linker Script `scripts/Make.defs`: StarPro64 Makefile `src/Makefile`: StarPro64 Makefile `Kconfig`: StarPro64 Config `configs/nsh/defconfig`: Build Config for `starpro64:nsh` ### Documentation `platforms/risc-v/eic7700x/index.rst`: Added StarPro64 to EIC7700X SoC `platforms/risc-v/eic7700x/boards/starpro64/index.rst`: Building and booting NuttX for StarPro64 ## Impact This PR is needed to support NuttX on StarPro64 SBC. No impact on existing code, since the StarPro64 source files are not used by existing code. ## Testing We tested the NuttX Build on StarPro64 SBC via U-Boot Network Boot (TFTP): - [Build Log for StarPro64](https://gist.github.com/lupyuen/e2ff3e92635ef016af2f672bef970f72) ```bash tools/configure.sh starpro64:nsh make ## Omitted: Build Initial RAM Disk, append to NuttX Kernel with padding, copy to TFTP Server ``` NuttX boots correctly to NSH Shell and passes OSTest: - [NuttX Log for StarPro64](https://gist.github.com/lupyuen/cadc99a689d30becb37e88c122094ba9) ```text NuttShell (NSH) NuttX-12.8.0 nsh> uname -a NuttX 12.8.0 ffef486b59 Mar 5 2025 03:52:12 risc-v starpro64 nsh> free total used free maxused maxfree nused nfree name 2057216 11632 2045584 33320 2042800 38 6 Kmem 20971520 720896 20250624 20250624 Page nsh> ls -l /dev /dev: crw-rw-rw- 0 console crw-rw-rw- 0 null brw-rw-rw- 16777216 ram0 crw-rw-rw- 0 ttyS0 crw-rw-rw- 0 zero nsh> ps PID GROUP PRI POLICY TYPE NPX STATE EVENT SIGMASK STACK USED FILLED COMMAND 0 0 0 FIFO Kthread - Ready 0000000000000000 0003056 0001040 34.0% Idle_Task 1 0 100 RR Kthread - Waiting Semaphore 0000000000000000 0001968 0000720 36.5% lpwork 0x80400100 0x80400148 3 3 100 RR Task - Running 0000000000000000 0003008 0001872 62.2% /system/bin/init nsh> hello Hello, World!! nsh> getprime Set thread priority to 10 Set thread policy to SCHED_RR Start thread #0 thread #0 started, looking for primes < 10000, doing 10 run(s) thread #0 finished, found 1230 primes, last one was 9973 Done getprime took 134 msec nsh> ostest Final memory usage: VARIABLE BEFORE AFTER ======== ======== ======== arena 81000 81000 ordblks 2 3 mxordblk 7cff8 78ff8 uordblks 2660 4570 fordblks 7e9a0 7ca90 user_main: Exiting ostest_main: Exiting with status 0 nsh> ``` -- This is an automated message from the Apache Git Service.
