Hi all, I got Linux running on our custom board and am in the process of learning how to build the final image to be burned on the flash.
To support our application I wrote simple device driver which maps the physical address space to user space. During development (NFS file system), it worked good enough. I could install/un-install it without any problem using insmod/rmmod. However, when I tried to install the module when using SELF ramdisk image, I get bunch of unresolved symbols error. What gives? I'm using exactly the same kernel so the symbols should be there whether I use NFS root or SELF ram disk as root. Any help will be appreciated. # insmod FPGA_module Using /lib/modules/2.4.20/FPGA_module.o insmod: unresolved symbol remap_page_range insmod: unresolved symbol create_proc_entry insmod: unresolved symbol ioremap insmod: unresolved symbol iounmap insmod: unresolved symbol proc_mkdir insmod: unresolved symbol remove_proc_entry insmod: unresolved symbol sprintf insmod: unresolved symbol printk =============================================================== Brian S.
