Hi all,
I choose DVRRDK_04.00.00.03 as my development environment. I connected a USB wireless network card to USB0 of my customer DM8148 board. But the wireless network connect often be broken. The console prints the message as floows:
ti81xx_interrupt 881: CAUTION: musb0: Babble Interrupt Occured
ti81xx_interrupt 882: Please issue long reset to make usb functional !!
ti81xx_interrupt 971: Babble: devctl(98) set session to resume
