hi
I want to enter DM355 USB test mode to test the usb diagram for both host and device. Following is the bash file I wrote to test the packet.
#!/bin/sh
echo "test start!"
# 0x0 is device mode, 0x1 is host mode?
./areg -w /dev/areg 0x01c64460 0x0
# write packet
i=0
while [ $i -lt 9 ]
do
i=`expr $i + 1`
echo $i
./areg -w /dev/areg 0x01c64420 0x0
done
i=0
while [ $i -lt 8 ]
do
i=`expr $i + 1`
echo $i
./areg -w /dev/areg 0x01c64420 0xaa
done
i=0
while [ $i -lt 8 ]
do
i=`expr $i + 1`
echo $i
./areg -w /dev/areg 0x01c64420 0xee
done
./areg -w /dev/areg 0x01c64420 0xfe
i=0
while [ $i -lt 11 ]
do
i=`expr $i + 1`
echo $i
./areg -w /dev/areg 0x01c64420 0xff
done
./areg -w /dev/areg 0x01c64420 0x7f
./areg -w /dev/areg 0x01c64420 0xbf
./areg -w /dev/areg 0x01c64420 0xdf
./areg -w /dev/areg 0x01c64420 0xef
./areg -w /dev/areg 0x01c64420 0xf7
./areg -w /dev/areg 0x01c64420 0xfb
./areg -w /dev/areg 0x01c64420 0xfd
./areg -w /dev/areg 0x01c64420 0xfc
./areg -w /dev/areg 0x01c64420 0x7e
./areg -w /dev/areg 0x01c64420 0xbf
./areg -w /dev/areg 0x01c64420 0xdf
./areg -w /dev/areg 0x01c64420 0xef
./areg -w /dev/areg 0x01c64420 0xf7
./areg -w /dev/areg 0x01c64420 0xfb
./areg -w /dev/areg 0x01c64420 0xfd
./areg -w /dev/areg 0x01c64420 0x7e
# enter test mode
./areg -w /dev/areg 0x01c6440c 0x8000000
# set TxPktRdy ready
./areg -w /dev/areg 0x01c64410 0x20000
echo "test done!"
Here are the questions I want to know
1. Can I run this file to test both device mode and host mode? How?
2. On device mode, Do I need to send command SET_FEATURE to DM355 first? On host mode, what do I need to do before run the scipt?
3. Is there any mistake I make or Can you give me some advice? as I can't see the diagram by running the scirpt.
Thanks,
Best regards,
Jian
