Message: 63931   




I find that lrzsz tools do not work for BF531. Anybody testes the lrzsz tools under BF533-


Stamp ?


In my BF537 Board , lrzsz works well . But in my BF531 borad , it failed!


I copy the binary file "lrz","lsz" of BF537 to the BF531 filesystem , it still does not work


,.So I think it maybe something wrong with the Uart Driver of BF531.


I have googled something. it said that it is the problem of uart dma, but i do know how to


fix this problem !

the zmodem utils have been tested on a BF531 as well as the BF533-STAMP and are known to work.  please describe in detail what you are actually doing and how you think they are failing as well as your whole setup (software/development system/etc...).

I check my board tonight. I forgot that i used the different crystal , 24.576M for BF531 and 25M for BF533.


I changed the crystal value in uclinux ,and lrz lsz work well .


Thank you !
