Hi Team,

I am working on Dm3730 custom board ,as a part of my project i just want to send 1kb of buffer to the UART2 but i'm receiving only 64bytes of data at the U-boot.

At kernel, i am able to send and receive full 1Kb of data.Please help me regarding this ..............

Hi Livin,

I advise you to check the UART buffer size in the u-boot. If it is possible for the sender site you could try to send the data in parts of 64 bytes.

Hi Tsvetolin Shulev,

Thanks for the reply.

The buffer size is 64 bytes by default, and i don't have control over receiving side.

The data will be sent all at once(around 1Kb).
