Device driver for 5402 DSK on board UART using DSP/BIOS

Started by pradbelur January 24, 2002
Hi all,

We are developing a device driver for the 16C550CFN uart,
present on the 5402 DSK.

The driver is based on the streams IO model of DSP/BIOS.We are facing
the following problem: When the SIO_get internally calls the DXX_issue
function , the issue function is being called twice for one
invocation of SIO_get.Inside DXX_issue we are having a mechanism for
maintaining the order of the buffers for 2 buffers.These buffers were
alllocated statically using the configuration tool.

The streams are also statically configured.

If any one of u has a solution for this, please reply at the earliest. Regards,
