Hi all. These days , I haved been troubled by a trouble. As I am a new boy
who play with linux and PowPc603e(MPC8247). I have no ideal to solve it.
The request below give rise to the problem.I have some boards equiped with
MPC8247 and FPGA without storage media which used as a PCI interface. So when
the linux bootup before initialize the PCI, the code of FPGA will download. I
append the FPGA code file in the Kernel section '.init.text'. when linux bootup
firstly it check the board type(different board type would download different
code), and download fpga code. More board types lead to more FPGA code. I
append them all in the section of '.init.text'. when the total size of the
code reach out 2M. The error occured. I read the '__log_buf' the kernel access
some bad area. As the powerpce603 will map 16M address use two bat, how and why
the problem occured, and how to solved it .
I kown it can download in the bootloader who read the FPGA image in the
flash.But when the the flash is blank and the systerm boot from the tftp using
a Muti-file image, another proble will occured.
You advice will helpful! Sorry for my poor
english!
