Hello,
we want to do a comparison of running FreeRTOS on the Banana Pi with Jailhouse
and running FreeRTOS bare-metal on the Banana Pi for a study-project at
Hochschule Esslingen. We were successfull in doing this with the Jailhouse
hypervisor, but we currently didn't find a way to boot FreeRTOS bare-metal on
the banana pi. So our question is, if there's a way to boot the
freertos-demo.bin from the freertos-cell bare-metal on the banana pi.
Conceptually, you need to make the demo executable at a different physical
address (it's configured to run from address 0, but RAM starts at 0x40000000 on
the board), and then you could load it there via u-boot and jump to it. You also
have to ensure that the demo configures its uart itself and doesn't rely on the
root cell to do anything. I don't recall if that is already the case. Hans may
tell more about that.
