+# c906_little bsp
+This BSP is a coprocessor in the cv18xx series processor, using RISCV C906 @ 700Mhz.
+Features:
+- No MMU
+- Integrated Floating-point Unit (FPU)
+
+## Toolchain Download
+Download the toolchain for `riscv64-unknown-elf-gcc`: [https://occ-oss-prod.oss-cn-hangzhou.aliyuncs.com/resource//1705395512373/Xuantie-900-gcc-elf-newlib-x86_64-V2.8.1-20240115.tar.gz](https://occ-oss-prod.oss-cn-hangzhou.aliyuncs.com/resource//1705395512373/Xuantie-900-gcc-elf-newlib-x86_64-V2.8.1-20240115.tar.gz)
+
+> Note:
+Current BSP only supports Linux compilation.
+
+After correct decompression, add the local path of the `riscv64-unknown-elf-gcc` toolchain to `EXEC_PATH` in `rtconfig.py`, or specify the path through the `RTT_EXEC_PATH` environment variable.
+
+```shell
+$ export RTT_EXEC_PATH=/opt/Xuantie-900-gcc-elf-newlib-x86_64-V2.8.1/bin
+```
+
+## Compilation
+1. Dependency Installation
+
+```shell
+$ sudo apt install -y scons libncurses5-dev wget flex bison
+```
+
+2. On Linux platform, execute:
+```shell
+$ scons --menuconfig
+```
+
+Choose the target development board type that needs to be compiled:
+```shell
+Board Type (milkv-duo)  --->
+    ( ) milkv-duo
+    (X) milkv-duo256m
+```
+
+It will automatically download env related scripts to the ~/.env directory, then execute
+```shell
+$ source ~/.env/env.sh
+$ pkgs --update
+```
+After updating the software packages, execute `scons -j10` or `scons -j10 --verbose` to compile this BSP. Or use the `scons --exec-path="GCC toolchain path"` command to compile directly while specifying the toolchain location. If the compilation is correct, the rtthread.elf file will be generated.
+
+After the compilation is completed, the script automatically calls the `combine-fip.sh` script for packaging, and generates `fip.sd`, which is the c906_little file for SD card startup.
+
+The first time the `combine-fip.sh` script is called, it will automatically download the required `opsbsbi`, `fsbl`, `uboot`, and other related files to the `bsp/cvitek/cvitek_bootloader` directory, please be patient.
+
+After downloading, it will automatically decompress and compile. Subsequently, when compiling the same type of development board again, only the relevant files will be called to package and synthesize `fip.bin`. If you need to manually compile the related `cvitek_bootloader` files, you can execute `bash build.sh lunch` in the `bsp/cvitek/cvitek_bootloader` directory to choose the corresponding development board for compilation.
+
+## Running
+1. Divide the SD card into 2 partitions, the 1st partition is used to store bin files, and the 2nd partition is used as a data storage partition, with the partition format being `FAT32`.
+2. Copy the `fip.bin` and `boot.sd` from the root directory into the 1st partition of the SD card. Subsequent firmware updates only require copying the `fip.sd` file.
+Where:
+- fip.bin: fsbl, opensbi, uboot, c906_little packaged bin file
+- boot.sd: bin file packaged by the main kernel
+
+After updating `fip.sd`, restarting will show the output information on the serial port:
+```shell
+HW_HEAP_BEGIN:83f74dc0 RT_HW_HEAP_END:84000000 size: 569920
