I was thinking differently, could it be that casting...as shown above...introduce this behaviour? what if you just point to the address...directly without any "container" such as struct foo?
printk(KERN_DBG "value TEST1: 0x%lx\n", readl(test_foo->TEST1)); printk(KERN_DBG "value 0: 0x%x\n", readw(&test_foo->a1[0]); printk(KERN_DBG "value 1: 0x%x\n", readw(&test_foo->a1[1]);
in the above statement, it means "take the address of a1[0 and read some bytes from that address", right? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
