Yocto Support?

[swanav]

Support for Yocto-Linux based devices would be very useful and would suit my requirement for a WiFi/BT Combo for a custom board.

Thanks for your feedback. There is no plan to support Yocto linux in near future. We will keep it in consideration though.

Thanks

@swanav I think you should just write a simple recipe in your layer to get the sources and build the module. Pretty simple when doing yocto stuff, no more than few lines are required :-)

This would indeed be very nice

Hello @Oquirella,

Many of the customers have ported the solution with Yocto.
Worth to check issues to understand how the porting happened:
#101
#128

Also, PR: #130 for Beaglbone Black (BBB)

In general, Yocto boards have to

1. Configure device tree so that the expected device is correctly set-up.
2. If any user space application can be used to test that the device driver provided by Linux is working correctly.
3. Additional pins to be configured for ESP-Hosted solution as mentioned in porting guide
4. For only SDIO transport, Additional Pull-ups to be added, If required any, as per https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/sd_pullup_requirements.html
5. Hardware and software setup as per Hosted documentation and porting guide.

The problem with Yocto is that no specific configuration works for all the SoCs. Why? Because, the peripherals and their Pin Controls differ. Device Trees differ across the SoCs. No single Yocto config will work for any other SoCs as is.

Be it Yocto or Non-Yocto, the procedure for porting remains the same.
The porting should be given some efforts as mentioned in the Porting Guide and you should definitely get the ESP-Hosted working with the least efforts.

If you are stuck at any place while porting, just raise an issue. We will certainly help you out.
