hi,

i am using sabrelite board, and right now i developed the UART driver hal code and following are the working results,
i.e.
data handling method:
for read and write i am using DMA mode. and i created thread for transmit as well as receive,
transmit/receive handle i am checking the data size if it is 0 then i am sending the sem_post,
so that in read/write sem_wait will reales.

TEST Procedures,
1)very first time i am able to read the data from the teraterm
2)i try to write the data to teraterm,
3)again i try to read the data from teraterm, but this time i am not able to read it?

so anyone faced this kind of problem, kindly help me to solve this issue.

With Regards
Maddy
