My new Hawkboard will not boot reliably. What is wrong?

This is a known issue with the latest Hawkboard hardware revision and is being investigated. Earlier versions of the Hawkboard hardware used an earlier OMAP-L138 silicon revision plus industrial spec parts for many components in the BOM which have now been populated with commercial spec parts in the latest shipping board revision.

Some of the most recent batch of Hawkboards appear to have operational stability issues as a result of these BOM changes straight from the factory which affect all OSes. MPC Data recommends that you contact your hardware supplier and check the Hawkboard Forums if your board exhibits boot issues.

The OMAP-L138 CPU on the Hawboard runs hot to the touch. Is there a fix?

This is a known issue with the Hawkboard hardware which appears to be caused by the way that the [SW1] Boot Selection Logic is implemented in hardware. When the default NAND boot option is selected SW1-1 is ON which pulls VPIF_DOUT12 low however the CPU is still attempting to drive the PIN.

The latest release of the MPC Data BSP (V1.1) addresses the issue by modifying the PINMUX settings. The operational CPU temperature can also be reduced to normal in most cases by switching SW1-1 OFF once the board has booted successfully.

Remember to set SW1-1 to ON again each time you power cycle otherwise the board will not boot from NAND!.

The SD Card is not detected when the write protect is on. Why is this?

This is a known issue and is being investigated. For now, you can only use an SD card with the write protect off.

I have enabled the USB host or function driver, but it does not work. Is there something else I need to do?

Depending on the type of USB cable used, you may also need to set the Jumper JP1 to configure the USB direction. Check the Hawkboard documentation for details on this.

Is there anything I can do to speed up the build?

In many cases, a full build is not required. In general, a full 'sysgen' is only required when adding or removing components from the catalog (i.e. changing the SYSGEN_* variables). When modifying components (i.e. BSP_* variables ) or code inside the BSP platform directory, you can usually get away with a 'Build BSP and Subprojects'. Finally, if just changing image configuration flags (i.e. IMG* variables), then a 'Make Run-time image' will often work. A good way to remember this is to be aware which type of variables (SYSGEN_*, BSP_*, IMG*) have changed, and see that the build type required matches these variable names.

I get an error installing the SDK with Visual Studio 2008. Is there a workround?

Depending on the way that VS2008 and other Windows components are installed you can get an error at the end of the SDK install. Select a Custom Install and deselct the Documentation (which does not actually install anything anyway) then re-run the installer.
