- Adjusted slot assignments in to reflect new peripheral mappings. - Updated to validate new OpenC906 configurations, including generator and profile checks. - Modified to reference the new Std-series VexiiRiscv generator. - Changed cache maintenance instructions in to align with C906 specifications. - Revised assertions in to account for internal unit removals. - Updated to reflect changes in peripheral interface counts and policies. - Added new test file to ensure preservation of the frozen HP configuration in the Std-series generator.

HP RT-Thread BSP
This directory owns the single-hart RV64 M-mode BSP and deterministic kernel
acceptance application. Upstream RT-Thread is installed at the revision in the
dependency lock under .cache/; it is not edited or copied into project source.
SCons runs on a staged BSP below build/<variant>/hp-rtthread/.
Run make setup-hp-rtthread, then make CONFIG=configs/ci/ihp130-rtthread.mk SIMU=VERILATOR hp-rtthread-sim. The test uses UART1 and the internal C906
CLINT (time CSR plus MTIMECMP at 0x0C004000) and PLIC machine context 0 with
the mailbox doorbell at source 18. Peripheral accesses remain 32 bits. Static threads
exercise RV64 integer state, timer preemption, semaphore/message queue behavior,
timeouts, and an LP-to-HP mailbox interrupt. LP validates the final mailbox
response and owns SYSCTRL TEST_STATUS. A banner alone is not a pass.
The authoritative contract is HP platform. RT-Smart, networking, filesystems, floating-point task qualification, and PPA are outside this test. Self-owned C follows the repository C policy; the locked upstream OS is third-party material. No operating-system dependency enters crt.
