[U-Boot] Uboot for PowerPC MPC8313

[Ankur Singh]

Hi,

We are developing application at PowerPC MPC8313E.

For testing of peripherals at power on of the device, we are using U-boot Version – 1.1.6).  This is an old project and we are only upgrading few of the functionalities.
The reason I have contacted you is, I’m trying to test UART3 (it’s a memory mapped IO, driven from a eLBC module via chip selection and all).

Somehow I’m not able to test from the u-boot how to test this memory mapped IO. I’m looking to transmit and receive few character to HyperTerminal and conclude whether its working or not?
My questions are
1.       Is it possible to test this UART (memory mapped IO) in such a manner?
2.       If yes, can u guide me how to test with some reference code or something?

We have been struck here for a week and tried everything but I think somewhere I’m lacking proper guidance (1st time I’m developing something on Linux and powerPC)

Thanks for any suggestion..

Regards,

Ankur Singh
