Currently, we have problem communicating with the device attached to the USB port of TI DM8148. Below are the configurations.
Downloaded the latest Linux PSP - DM814x Linux PSP - 04.01.00.07. The MUSB controllers on the DM8148 is configured as HOST.
- Compiled the uImage.
- Connected an USB wireless modem kit to the usb1 port of DM8148 EVM ( Rev C )
- Inserted the jumper to J22
- The USB wireless modem was identified as is mounted under /dev directory.
Two issues:
1. The below error message is displayed when a software reset on the modem side is issued.
ti81xx_interrupt 880: CAUTION: musb0: Babble Interrupt Occured
ti81xx_interrupt 881: Please issue long reset to make usb functional !!
2. Controls to the Linux console terminals (telnet, minicom) are not responsive when performing the reset on the modem side.
Please, could someone guide if any configuration is needed
