Hi,
I just tried to boot a freshly built u-boot.kwb using UART boot on a
Kirkwood box (IB-NAS6210), but to no avail. An old backup image does
not boot either.
After scratching my head for quite some time, I found this change in
commit f4db6c976cf ("arm: mvebu: Add runtime detection of UART
(xmodem) boot-mode") to kwboot.c:
@@ -652,6 +654,14 @@ kwboot_img_patch_hdr(void *img, size_t size)
hdr->blockid = IBR_HDR_UART_ID;
+ /*
+ * Subtract mkimage header size from destination address
+ * as this header is not expected by the Marvell BootROM.
+ * This way, the execution address is identical to the
+ * one the image is compiled for (TEXT_BASE).
+ */
+ hdr->destaddr = hdr->destaddr - sizeof(struct image_header);
+
if (image_ver == 0) {
struct main_hdr_v0 *hdr_v0 = img;
Reverting this change makes kwboot work again for me.
I don't know what the correct fix is. Should we change hdr->destaddr
only for header version 1? (Orion and Kirkwood use header version 0,
right?)
