Message-ID: <CAAfyv37Xm7MAuTToGeDr56gTYBVy6ZJTnXf=vcX3HmZfCoNkZw@mail.gmail.com> (raw)
In current next there is issue with usb command on panda board:
barebox@Texas Instrument's Panda:/ usb
USB: scanning bus for devices...

It is crashing in ehci_halt() in first ehci_read call. IMO ehci_read
access wrong memory (that is reason do data_abort?)
I have rev. A2. Any ideas?
Thanks,
Marek
