It this is expected, it seems like a *really* bad idea. It's cost me having to reload 6M images at 115200 twice now.

Hi JC,
It is a configuration/design decision: see include/command.h line 46ff, struct cmd_tbl_s, field "repeatable". This is configured via the U_BOOT_CMD macro.
Sometimes it is nice (e.g. sequencing through memory dumps), sometimes it bites (you found one of those!). IMHO, it is enabled in places where it would be better to rely on command line recall rather than the repeat function.
I think the repeat functionality predated the command line recall functionality, so it use to be more desirable to repeat the command because there wasn't an alternative way to repeat the command.
Best regards, gvb
