I am using BF526 with visual dsp++ 5.0 update 10.0.
my system have usb peripheral.
now ,I want to update update my firmware through usb peripheral.
how can i do it ?
can give me some suggests an examples?
Sorry for the late reply.
The default Boot modes supported by the BF52x processor doesn't include USB. However, one can achieve firmware upgrade using the second stage loader concept.
The Second Stage Loader application should be first booted (eg: boot from SPI flash) and this application should now communicate with the USB device in order to recieve the boot stream, analyze and update the SPI flash using the underlying flash driver.
We dont have the sample code to show this. Nevertheless, the Boot ROM sources and the USB drivers are all available in the VDSP++ installation and that should help you as a starting point along with the HRM to understand about Boot and USB peripheral.
Let me know if you need any clarifications.
