I have the 2.6 Kernel running now. Here are few of the things that i did to make it happen: 1: make ads8272_defconfig 2: edit .config to add the follow: CONFIG_SERIAL_CORE=3Dy CONFIG_SERIAL_CORE_CONSOLE=3Dy CONFIG_SERIAL_CPM=3Dy CONFIG_SERIAL_CPM_CONSOLE=3Dy CONFIG_SERIAL_CPM_SCC1=3Dy CONFIG_SERIAL_CPM_SCC2=3Dy 3. In u-boot, set the bootargs to bootargs=3Droot=3D/dev/ram rw console=3DttyCPM0,115200 4.Modify the file arch/ppc/platforms/pq2ads.h, // #define BCSR_ADDR ((uint)0xf4500000) #define BCSR_ADDR ((uint)0xff080000) Thanks! ashutosh On 7/16/05, Mike Rapoport wrote: > SIP COP 009 wrote: >=20 > >Hello, > > > >We have a MPC8272 Eval Board which came with Linux 2.4 and U-boot.
