Accumulated patchsets for bsp/cvitek (#8968) 
* bsp: cvitek: kconfig: add wdt for cv18xx_riscv

Add Watchdog timer in Kconfig.

Signed-off-by: Chen Wang <unicorn_wang@outlook.com>

* drv: cvitek: remove using macro from source file

Building of source file should be controlled by SConscript,
but not in source file itself.

Signed-off-by: Chen Wang <unicorn_wang@outlook.com>

* bsp: cvitek: kconfig: add i2c for cv18xx_riscv

Add I2C in Kconfig for c906B.

Note, the IRQ# is different from that of c906L.

* bsp: cvitek: kconfig: add rtc for cv18xx_riscv

Add RTC in Kconfig for c906B.

Signed-off-by: Chen Wang <unicorn_wang@outlook.com>

* bsp: cvitek: fix channel issue for pwm driver

The original code confuses the concepts of controllers and channels.
Fixed it and do some code cleanup.

Signed-off-by: Chen Wang <unicorn_wang@outlook.com>

* bsp:cvitek: add i2c pinmux config for cv18xx_riscv

Pinmux in driver code is controlled by SOC type, bcos driver
code should be general and support all pins defined by SoC.

Pinmux configuration in Kconfig is controlled by BOARD type,
bcos when we operate on board, it does not expose all chip-level
pin signals and we can only use part of them.

Following is I2C signals exported by duo family. Details see
https://milkv.io/docs/duo/overview.

Note: we have not added support for duo-S.

支持芯片

针对算能系列 RISC-V 芯片的 bsp，包括：

  • 大核
芯片名称 芯片架构 内存大小 默认日志串口 备注
cv180x RISC-V C906 64MByte uart0 支持 MMU， 支持 RT-Thread 标准版 和 RT-SMART 模式，默认运行 RT-Thread 标准版本
cv181x RISC-V C906 或 Cortex A53 通过硬件 IO 二选一 64MByte uart0 支持 MMU， 支持 RT-Thread 标准版 和 RT-SMART 版，默认运行 RT-Thread 标准版本
  • 小核
目录 内存大小 默认日志串口 备注
c906-little 与大核共享 uart1 无 MMU，运行 RT-Thread 标准版

注：异构芯片需单独编译每个核的 OS

编译

异构芯片需单独编译每个核的 OS，在大/小核对应的目录下，依次执行:

  1. 开发板选择 Linux平台下，可以先执行：
$ scons --menuconfig

选择当前需要编译的目标开发板类型

Board Type (milkv-duo)  --->
    ( ) milkv-duo
    ( ) milkv-duo-spinor
    (X) milkv-duo256m
    ( ) milkv-duo256m-spinor
  1. 编译
$ scons

运行

编译成功后，会在 bsp/cvitek/output 对应开发板型号目录下自动生成 fip.bin 和 boot.sd 文件，其中大核运行文件在 boot.sd 中，小核的运行文件在 fip.bin 中。

  1. 将 SD 卡分为 2 个分区，第 1 个分区用于存放 bin 文件，第 2 个分区用于作为数据存储分区，分区格式为 FAT32。
  2. 将根目录下的 fip.bin 和 boot.sd 复制 SD 卡第一个分区中。
    • fip.bin：fsbl、 opensbi、uboot、小核运行文件打包后的 bin 文件
    • boot.sd：大核打包后的 bin 文件

FAQ

  1. 如遇到不能正常编译，请先使用 scons --menuconfig 重新生成配置。

  2. 错误：./mkimage: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

可在 http://security.ubuntu.com/ubuntu/pool/main/o/openssl 下载 libssl1.1_1.1.1f-1ubuntu2_amd64.deb 文件后安装即可解决。 或使用以下命令下载安装:

$ wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2_amd64.deb
$ sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2_amd64.deb
  1. 如发现切换开发板编译正常，但无法正常打包，请切换至自动下载的 cvi_bootloader 目录，并手工运行 git pull 更新，或删除该目录后重新自动下载。
