Dear all, I'am faced with the task of migrating a thirdparty BSP named Intrinsyc Cerfboard255 from Wince4.2 to Wince5.0. This BSP supports the Wince4.2 OS on the customized Cerfboard running Intel XscalePXA255 processor.The board has the following fetures. The CerfBoard employs an extremely small single board computer featuring the powerful, highly integrated and power efficient Intel XScale PXA25x microprocessor. It includes 32 MB of Flash, 64 MB of SDRAM, an Ethernet controller, USB (client) support, a Compact Flash interface (CF+), and three serial ports. So,can anyone advise me on how to start the migration,as I'am not finding much help from MSDN.Also,I've no access to the Intrinsyc BSP as it is not shipped with Microsoft PlatformBuilder.
