embOSView over USB (instead of UART)

felix.kramer · Apr 8th 2010, 2:42pm

We are planning to use ATMEL AT91SAM7 (ARM7) controller together with embOS. I am short with pins, therefore I am thinking about using the USB device interface with its dedicated pins as debug interface. ATMEL supplies a USB framework and code to implement CDC serial driver (virtual com port). Any suggestions or hints, if this configuration will work together with embView?

There is an older thread with related topic about debugging over TCP/IP.

Hello Felix,

with ARM7 you can use DCC instead of Uart. DCC communication works via the JTAG port.
We will also have a similary solution for Cortex M3 (which has no DCC) in near feature.

Please have a look in the RTOSinit.c, there you find the DCC code and coresponding
compiler switches. If you have any problems to use DCC please let me know.

Does this work for you?

Regards,
Til

What do you exactly want to do? If you want to use a webcam in your application you have to handle it in your application. It is not related to embOS. But you can use emUSB to communicate with your webcam.
