Dear All: My board's cpu is freescale 8247. I debug the linux kernel 2.4.26 with BDI2000 and ppc_6xx-gdb on it. My linux kernel text base on 0xC0000000, so some global variable at 0xCxxxxxxx virtual address. Now the problem is that I can not print the global variable's value, when i use "p" command in gdb: p /x ga. gdb always tell me it's zero, even if I directly print the content in the ga's address. But if I evaluate the ga's value to a local variable in programm, then print it in gdb, it can get me the correct value. It seems the global variable was processed correctly. But Why I can not get the value? where the global variable stored while kernel running?
