Are you referring to the u-boot or Linux 'reset command'? I assume u-boot.
I was able to find a 'reset' u-boot bug associated with our older u-boot (I could not readily find the version), but this should be fixed in our newer u-boot release. FYI, latest DVSDK includes u-boot 1.20
Hi, Juan
I've also encounted this problem. and the worse is there are no messages displayed in the HyperTermial when the DM6446 EVM is powered on.
Actually I used 2 commands "erase all" and "reset" in the U-boot shell, and after that the U-boot didn't boot.

P.S. the previous boot information is attached here.

Hi, Paul
Thank you for your reply.
This problem has been fixed by following these steps.
1. Flash the newer u-boot file "u-boot-567-nor_s3_4_fix.bin" by using "DVFlasher_1_10.exe" through UART.
2. Burn the "uImage" to NOR flash by using the following commands and the S3 should be "1111111111" when burning.
DaVinci EVM # tftpboot 0x80080000 uImage
DaVinci EVM # erase 0x2050000 22fffff
DaVinci EVM # cp.b 0x80080000 0x2050000 0x200000
However, I can't find the verify answer button below probably because I'm not the starter of this post, so sorry for that.
BR.

P.S. I tried the u-boot-1.2.0, but there are no responses in Hyperterminal, does this version of u-boot not match TMDXEVM6446?
