Hi,

I port u-boot last version on my board with SH7785. My board has no serial port (SCIF's are not connected).

Therefore i try to communicate over a pci2s-card which has a ns16650 chip.

i debug with Lauterbach-Debugger and can see the character in THR/RHR register.

i can receive the character but can not send any character. though I write the character in the THR-register.

i have no more idea.

Thanks, for any clue

Best regards, S.Altunbas
