how to get bareboard driver code (ex: USB, ethernet, PCIE ...) for P2020 and MPC8378?

[jingyibin]

I use CodeWarrior V10.5.1 to debug my P2020 RDB, but I find that there is no bareboard driver for USB, ethernet and PCIE which I need to access to for my next-step debug. How could I find these bareboard driver?

There are no bare board drivers for the P2020 or MPC8378 USB, Ethernet or PCIe.

Look at recommended initialization sequence for USB, Ethernet and PCIe in the P2020 Reference Manual:

See the Sections 18.6.1 and 18.8.1 about USB initialization.

See the Section 14.6.3 about Ethernet and the Section 16.13 about PCIe.

Look at recommended initialization sequence for USB, Ethernet and PCIe in the MPC8379 Reference Manual:

See the Sections 20.6.1 and 20.8.1 about USB initialization.

See the Section 18.6.2.1 about Ethernet and the Sections 14.5 and 15.7 about PCIe.

Have a great day,
