Since you seem to have a binary meant for UART booting, yes, you might try sending it to the board; with any luck that'll allow you to inspect and possibly revert your U-Boot environment into what it was before the bricking. As to how... any serial app with Xmodem should work, I presume. If the transfer starts, chances are the image will run automatically.
No, any app doing Xmodem will not work. In order to turn the Marvell Kirkwood romcode into UART boot mode, you have to send a series of magic bytes to the UART. This is what kwboot does before sending the binary using the Xmodem protocol.
Thanks for the correction -- however, it was done already in a private e-mail exchange with JPT, where indeed the requirement became "any app which can send files in raw as well as xmodem modes".
Best regards,
Thomas
Amicalement,
