[U-Boot-Users] FFUART problem

[U-Boot-Users] FFUART problem

[Petre Pircalabu]

Hello,

I have a problem regarding the FFUART of a PXA255 processor. U-boot
doesn't seem to accept any characters sent from the terminal (i'm
currently using hyperterminal) even after I cleared the RDH bit in the
PSSR. Did someone encountered this problem?

thanks,

Petre

Is it a hyperterm problem?  Did you verify hyperterm is actually sending data?  A classic problem is that Windows has handshaking enabled and it is waiting for a handshake.  Make sure both software and hardware handshaking is disabled.  (If your board supports handshaking, this would be a test.  If it doesn't, this is essential).

[U-Boot-Users] FFUART problem

[Petre Pircalabu]

No, the hyperterminal was configured for 19200 8N1 with no handshaking.
I've also tried minicom and there is the same problem.
I used also the skyeye simulator to test the program and it stops in
function serial_getc() al line 166.
166             while (!(FFLSR & LSR_DR))

thanks,

Petre

this is what I get from the serial port:

Attach a scope. Check if you see the characters on the wire.  If  you
do,  trace  them  on  your board. Are you sure your hardware is fully
functional?
