I'm still using version 2130, i noticed a speed bug when reading and writing seagates rom in serial boot mode.
If i choose 460800 as baud rate, it ignores it and uses default 38400 speed.

As someone of you noticed the same bug on last 2140 version?

In which model this happened ?
I have never encountered this problem in 2130.
Try to clean com pinout,and bend the inner two pins a bit so it sure touch MRT connector.

I've countered this issue on Granada drive (ST2000DM001-9YN164 pcb 100664987).
I'll clean com contacts and try again, but don't think is that the problem.

I cleaned my com, still same speed issue so it's definitely a bug.
I posted a video:

P.S.
I tried with old 170705 version, speed is fast. So 2130 has speed bug and very likely also last 2140 version.
Check it !!!

Can you set any higher baud rates manually? I would try 115200 bps. That's the highest baud rate supported by a "standard" UART, ie one where the baud rate divisor is equal to 1.

Ok, i just found out that is possible to read at full speed via boot mode even on last MRT version only if you select first a seagate family, if you select "F3 Arch (common)" the serial speed will be always setted at 38400 bps.
