hi

 

I have already set the right mode pins to 1000 for uart1 boot. and the serial port is good.

I checked the necessary files ,there is one point which I don't understand. what does this mean?

 

#LDR_FLAGS-BFIN_BOOT_UART := --port g --gpio 6(config.mk)

 

and if I use UART1 reside in PORT H,should I do some change to that?

 

 

 

thanks!

I don't think you need to change this flag, since according to http://docs.blackfin.uclinux.org/doku.php?id=toolchain:ldr-utils

 

--port and --gpio is used for HWAIT signal.
