Find and build a suitable kernel for your player from linux-mips.org, not from Fedora-MIPS. And, the user space packages are compiled against mips3 and abi=n32. I don't know if they can be run on 4KEc. Maybe you can have a try ;)
but kernel-vanilla-2.6.35-85.fc13.src.rpm , can't be compile to mipsel arch ? What I need ? With buildroot , I can build many apps (on fedora13) that work in the box, but boot a new kernel, I still have some doubts.
Booting a SoC is not a kernel-only job. It involves bootloader, the arch and board-specific codes and drivers. People usually start their hack from the vendor's code, the bootloader and the kernel with a lot of modifications, if the source is released. I won't suggest you start from vanilla or fedora kernel.
After , look at linux-mips.org, seems that we don't have RTD128x option neither realtek . Looking for a big patch between linux-2.6.12 and linux-2.6.12-VENUS , They do a specif configuration for REALTEK_VENUS:
--- tmp/linux-2.6.12/arch/mips/Kconfig +++ GPL/linux-2.6.12/arch/mips/Kconfig (...) +config REALTEK_VENUS + bool "Support for REALTEK Venus board" +# select BOOT_ELF32 + select IRQ_CPU# define this will include irq_cpu.o, and this is for the interrupt. + select REALTEK_VENUS_SERIAL_PORT + select DMA_NONCOHERENT + select GENERIC_ISA_DMA + select HW_HAS_PCI + select REALTEK_BOARDS_GEN + select SYS_SUPPORTS_32BIT_KERNEL + select SYS_SUPPORTS_LITTLE_ENDIAN + help + This enables support for the REALTEK Technologies Venus board.
and a new directory : +source "arch/mips/realtek-boards/Kconfig"
I saw the code, they change files like linux-2.6.12/init/main.c, and many in "core" code, which I'm not capable to port to a new kernel. Conclusion I can't build a new kernel for this devices. but I learn a lot, Thanks for your help.
