Hi,

thanks for the link but I think you misunderstood my question, my goal is to have TF-A supporting multiple device configuration by packing all required DTBs into the one TF-A binary and do selection at bootup time by probing a gpio for example:

similar thing is implemented in u-boot for example:

https://github.com/u-boot/u-boot/blob/master/doc/README.multi-dtb-fit

Hi Ayoub,

TF-A supports both hardware and firmware device tree configurations. Usage of device tree configurations are explained in TF-A documentation[1]. If you need any further specific information, please contact us.

Thanks,
