Hi,Diwakar

       Thinks for your support. We have test DFU boot mode, but the transmission speed of DFU is slow. It takes about 10 minutes to transfer tinyrootfs, so we don't use DFU to burn. Has TI tested how long it takes DFU to transfer a default system? What is the speed of the DFU under normal test conditions?

Zhang

Hi Zhang 

In dfu boot mode we are getting upto 167KByte/sec 

This the best which we can get , there are various factor involved usb driver stack class driver stack and also in DFU only one end point is getting used which is end point 0.

Hi Zhang 

Do you still have issue on this? the best would be to use the DFU only if you dont want to use SD.

Hi,Diwakar 

      Thanks for your support.We see that the AM62 uses DFU to burn default system on sdk9.0. The speed is 167KByte/sec? Our systems and applications are upto 3G, if use DFU will take too much time.

Hi Zhang 

The other thing which i can think off in boot till linux using NFS boot and then you can copy the rootfs to the emmc by sending the normal linux commands via minicom/Tera Term  script
