simulate or testing GPMC configuration without final board

Abraham Varricatt

Hello,

We are developing an OMAP4460 board which has a NAND memory module (from Micron) as it's boot device. So far we've been working/testing application-level work with a pandaboard. Recently, I've been focusing my efforts to get the bootloader (Das U-boot) configured for our target board. The TI guys on the u-boot mailing list (especially Pekon Gupta) have been most helpful in assisting me.

Right now, I'm wondering if there is any way to simulate or test our configuration without the actual hardware. At the very least, the GPMC memory driver is new (untested on an omap4460, to my knowledge). Is there any tool or software available that could be used to test/verify this? Perhaps to pass on the u-boot binary into code composer studio and see if the proper registers get set or something?

Hello Abraham,

I have suggestions about your questions:

Q1: Is there any tool or software available that could be used to test/verify this?

Yes, the GPMC driver can be tested/verified by Lauterbach with TRACE32 software for debugging on OMAP. Lauterbach is a powerful tool for debugging, probably it is possible to have some limitations. You can use Lauterbach for debugging of SW on alive stage of development. Lauterbach offers also to debug on a multi-core system running an OS to do things like set breakpoints, step through code, watch variables, dump memory contents, dump register values. For more information see this link http://www.omappedia.org/wiki/PandaBoard_JTAG_Debugging

Q2: Perhaps to pass on the u-boot binary into code composer studio and see if the proper registers get set or something?

Yes, You can use CCS to see the settings values in the GPMC registers. However, I think it is necessary to connect the hardware. If you have OMAP4460 panda board you can run your GPMC driver and check the GPMC registers in CCS.

Best regards,

Yanko

Hello Yanko,

We don't have a JTAG debugger with us at the moment, so using Lauterbach is not really an option. I was hoping for something else, but it looks like I'll need to wait for my hardware.

Thanks,
