The 8xx CPM configuration in 2.4.4 release from DENX has more options than any other release, including 2.4.21-pre3. For example, CONFIG_SMC1_UART is in 2.4.4 (DENX). My board uses SMC1 as UART. I almost needn't to change anything in 2.4.4-denx to make my 8xx CPM working. I'm trying to migrate the kernel to 2.4.21 and the kernel is stuck in my_console_write() and no any message is shown on the console. So I think the problem is in CPM settings. I enabled the following configuations for MPC8xx CPM. CONFIG_FEC_ENET=y CONFIG_USE_MDIO=y CONFIG_FEC_LXT971=y CONFIG_8xx_COPYBACK=y CONFIG_UCODE_PATCH=y
How can I set CPM correctly in 2.4.21? Any hints are greatly appreciated. - Shawn. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
