Hi, everyone
I'm using U-boot 2009-03. U-boot hangs in nand_init() function. I found the routine kmalloc in nand_scan_tail() cause U-boot reset.
int nand_scan_tail(struct mtd_info *mtd) { int i; struct nand_chip *chip = mtd->priv;
if (!(chip->options & NAND_OWN_BUFFERS)) { chip->buffers = kmalloc(sizeof(*chip->buffers), GFP_KERNEL); }
if (!chip->buffers) return -ENOMEM; ........
U-boot displays message as follows :
NAND: data abort pc : [<31f902b4>]\0x09 lr : [<31fa084c>] sp : 31f5bee0 ip : 00000076\0x09 fp : 00000000 r10: 00001188 r9 : 00020000\0x09 r8 : 31f5bfdc r7 : 00000001 r6 : 00000000\0x09 r5 : 31fa42b8 r4 : 31fa4364 r3 : 31fa052c r2 : 00000064\0x09 r1 : 00000063 r0 : ffffffff Flags: NzCv IRQs off FIQs off Mode SVC_32 Resetting CPU ...
Where the malloc function is defined? Why the kmalloc() hangs the u-boot? Is there any configuation definition needed?
Thanks in advance.
