TODO: Add NuttX Arch for JH7110
|

We added Star64 JH7110 to NuttX with 3 Pull Requests...
|
||||
|
||||
[Fix any dependencies](https://github.com/apache/nuttx/pull/10019)
|
||||
1. First we fix any dependencies needed by Star64 JH7110. This PR fixes the 16550 UART Driver used by JH7110...
|
||||
|
||||
[First PR](https://github.com/apache/nuttx/pull/10069)

|
||||
1. Next we submit the PR that implements the JH7110 SoC as a __NuttX Arch__...
|
||||
|
||||
Create [nuttx/arch/risc-v/src/jh7110/Kconfig](https://github.com/lupyuen2/wip-pinephone-nuttx/pull/38/files#diff-36a3009882ced77a24e9a7fd7ce3cf481ded4655f1adc366e7722a87ceab293b)

[Add support for JH7110 SoC](https://github.com/apache/nuttx/pull/10069)
|
||||
|
||||
TODO: Add NuttX Board Star64
|
||||
We add JH7110 to the Kconfig for the RISC-V SoCs: [nuttx/arch/risc-v/Kconfig](https://github.com/lupyuen2/wip-pinephone-nuttx/pull/38/files#diff-9c348f27c59e1ed0d1d9c24e172d233747ee09835ab0aa7f156da1b7caa6a5fb)
|
||||
|
||||
[Second PR](https://github.com/lupyuen2/wip-pinephone-nuttx/pull/40)
|
||||
And we create a Kconfig for JH7110: [nuttx/arch/risc-v/src/jh7110/Kconfig](https://github.com/lupyuen2/wip-pinephone-nuttx/pull/38/files#diff-36a3009882ced77a24e9a7fd7ce3cf481ded4655f1adc366e7722a87ceab293b)

|
||||
Then we add the source files for JH7110.
|
||||
|
||||
Create [nuttx/boards/risc-v/jh7110/star64/Kconfig](https://github.com/lupyuen2/wip-pinephone-nuttx/pull/38/files#diff-76f41ff047f7cc79980a18f527aa05f1337be8416d3d946048b099743f10631c)

TODO: Generate defconfig
|
||||
[Add support for Star64 SBC](https://github.com/lupyuen2/wip-pinephone-nuttx/pull/40)
|
||||
|
||||
We add Star64 to the Kconfig for the NuttX Boards: [nuttx/boards/Kconfig](https://github.com/lupyuen2/wip-pinephone-nuttx/pull/38/files#diff-60cc096e3a9b22a769602cbbc3b0f5e7731e72db7b0338da04fcf665ed753b64)
|
||||
|
||||
We create a Kconfig for Star64: [nuttx/boards/risc-v/jh7110/star64/Kconfig](https://github.com/lupyuen2/wip-pinephone-nuttx/pull/38/files#diff-76f41ff047f7cc79980a18f527aa05f1337be8416d3d946048b099743f10631c)
|
||||
|
||||
And we add the source files for Star64.
|
||||
|
||||
1. In the same PR, update the __NuttX Docs__...
|
||||
|
||||
Add JH7110 and Star64 to the list of supported platforms:
|
||||
|
||||
[nuttx/Documentation/introduction/detailed_support.rst](https://github.com/lupyuen2/wip-pinephone-nuttx/pull/38/files#diff-d8a0e68fcb8fcb7e919c4b01226b6a25f888ed297145b82c719875cf8e6f5ae4)
|
||||
|
||||
Create a page for the JH7110 NuttX Arch:

|
||||
|
