I take these timings from u-boot. Is there any reason why these timings differs? Datasheet says nothing about any delay while loop for sending bootmsg. Here is my diff with the very small change: diff --git a/scripts/kwboot.c b/scripts/kwboot.c index e068660..bcb5972 100644 --- a/scripts/kwboot.c +++ b/scripts/kwboot.c @@ -34,8 +34,8 @@ static unsigned char kwboot_msg_debug[] = { 0xDD, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77 }; -#define KWBOOT_MSG_REQ_DELAY 1000 /* ms */ -#define KWBOOT_MSG_RSP_TIMEO 1000 /* ms */ +#define KWBOOT_MSG_REQ_DELAY 10 /* ms */ +#define KWBOOT_MSG_RSP_TIMEO 50 /* ms */ /* * Xmodem Transfers btw.: Now I see that the internal ROM bootloader could also boot from SATA device - this sounds interesting.
