bsp/cvitek: Increase the value of RT_NAME_MAX

2025-09-25T05:03:00Z

Otherwise report runtime error: [E/kernel.obj] Object name sys workq exceeds RT_NAME_MAX=8, consider increasing RT_NAME_MAX. (obj_name_len <= RT_NAME_MAX - 1) assertion failed at function:rt_object_allocate, line number:520 Increase the value of RT_NAME_MAX to 16 for c906B. The value of RT_NAME_MAX for BSP of C906L and ARM core already meet the requirement of more than 8. Signed-off-by: Chen Wang

bsp: cvitek: riscv: use marco for linker script

2025-04-22T01:48:53Z

Regarding link script, some memory offsets and sizes are different between the standard version and the smart version (such as "__STACKSIZE__", kernel start address, kernel memory size, etc.). Original solution is replacing link scripts and use INCLUDE, which is relatively complicated. This improvement uses macros to replace constants in the link script. The preprocessing mechanism provided by gcc is used to dynamically replace constant values during the build process. In addition, the kernel load address (the corresponding KERNEL_VADDR_START for smart) was originally configured as 0xFFFFFFC000200000, which is default value of riscv with kernelmap enabled (0xffffffc000000000) plus offset to skip over bootloader (0x200000). This caused a trouble: due to default bsp configuration is for smart, if we switched to the standard version and build, and then switched back to the smart version, the value of KERNEL_VADDR_START will be default back to 0xffffffc000000000, which is different from the original configuration value, resulting in the need to manually reconfigure it, which is easy to forget and cause problems. The current solution is to use the default value 0xffffffc000000000 in the configuration. Add offset to the code and link script when using it. This patch update the default .config and rtconfig.h for cv18xx_riscv. Signed-off-by: Chen Wang

bsp: cvitek: use rttpkgtool to replace cvitek_bootloader

2025-01-26T02:55:44Z

Originally, for riscv big and little cores under bsp/cvitek, after generating rtthread.bin, the cvitek_bootloader tool would be used to package it and generate fip.bin and boot.sd files that can be burned into sdcard. However, the cvitek_bootloader tool repository is relatively large, and it compiles and generates firmware such as fsbl, opensbi and uboot from the source code level. And when using it, it needs to be downloaded to the bsp/cvitek directory, which will introduce pollution to source files in the RTT repository under the original working path. The new solution uses rttpkgtool, which is similar to cvitek_bootloader, but it uses prebuilt firmware, so it is very small and does not introduce pollution to the source file.

bsp/cvitek: print arch info. during boot-up (#9919)

2025-01-16T14:33:55Z

Duo's CPU combination is more complicated: | BSP | B/L core| ISA | UART | | ------------- | ------- |---------------- |-------| | cv18xx_risc-v | Big | RISC-V C906 | UART0 | | c906-little | Littel | RISC-V C906 | UART1 | | cv18xx_aarch64| Big | ARM Cortex A53 | UART0 | Printing ISA and big and small core information during the boot process helps developers/testers determine the CPU and serial port corresponding to the current console. In addition, the RTT logo printing has already distinguished whether it is smart, so the bsp printing no longer distinguishes. Updated README to sync with this change. Signed-off-by: Chen Wang

bsp: cvitek: remove support for spinor/spinand

2025-01-08T22:54:14Z

Confirmed with milkv, only the sd card version is sold by default for duo in the market. The spi pins are provided through stamp holes, so that users can solder the corresponding components on their baseboard during secondary development. In order to simplify maintenance work, the mainline will only support the sd-card version and no longer support spinor/spinand. Updated config files the same in this patch. Signed-off-by: Chen Wang

bsp: cvitek: 906b: romfs -> diskfs

2024-11-27T02:45:00Z

ROMFS is Read-Only Memory Filesystem. But ext4/fat are not read-only. So renamed: - mnt_romfs.c -> mnt_diskfs.c - BSP_ROOTFS_TYPE_ROMFS -> BSP_ROOTFS_TYPE_DISKFS Signed-off-by: Chen Wang
