Why kernel uImage to be loaded at 32KB offset ?

Hi All, My board's physical memory starts at 0x8000_. The kernel uImage is loaded at 0x80008000. I have seen in many other boards the uImage is loaded at 32KB. Why is this mandatory to load uImage at 32KB offset? Please let me know. Thanks, Karthik.

Issue in ioctl func call of character driver.

Hi, I am new to kernel device drivers. I wrote a simple character driver built statically having the fops as shown: *static const struct file_operations mfcfpga65_usb_fops = {* * .owner = THIS_MODULE,* * .open = mfcfpga65_usb_open,* * .read = mfcfpga65_usb_read,* * .unlocked_ioctl = mfcfpga65_usb

Correct Place of calling a driver initialization function.

Hi, I am new to linux-kernel and am using kernel 3.1.6 and working on arm-SemiHosting(through USB) drivers. We are using SemiHosting to exchange/transfer data from the arm-board to the PC. Board details – Using ARM926e-js processor with 128MB SDRAM., Clock-33Mhz SDRAM Size = 128M CONFIG
