Does Zephyr support the 58 series?

Troubleshooting
1

Do the zephyr examples currently only exist in the main branch because chip adaptations for various series aren’t complete yet?

I noticed the following note in the bap_broadcast_src_with_classic_bt example’s readme:

BLE Audio Player (Source)

Source path: example/zbt/bap_broadcast_sink

## Supported Platforms

<!-- Which boards and chip platforms are supported -->

+ sf32lb52x

When compiling and flashing onto the 58LB, it seems that all HCI commands are timing out.

Use the 52-letter series for source, such as 52D or 52J. Do not use 525. The 58 series is an earlier chip and should not work for source.

Depending on the chip version of 58: 58A1 won’t work, but 58A2 should work in theory. If it doesn’t, applying a patch should fix it. Check whether you have 58A1 or 58A2. During compilation, there’s an option in menuconfig; if it doesn’t match, the device will fail to boot.

Latest SDK:
SiFli-SDK: SiFli-SDK

So, the 58A1 chip definitely can’t use applications related to Zephyr, right? If so, is SDK support available for developing LE AUDIO-related applications?

The ZBT example on the SDK mainline has not been officially released yet; we will verify its support across various platforms.
Additionally, zephyr (not sifive-sdk) has not yet been ported to the 58 series.
