Hi
I used china USB blaster.
10 hours for download.
Driver of USB blaster is WinUSB
C:\openocd-0.10.0\bin-x64\openocd.exe -d1 -f C:\openocd-0.10.0\scripts\interface\altera-usb-blaster.cfg -f C:\openocd-0.10.0\scripts\target\imx28.cfg
telnet a 127.0.0.1 : 4444
halt
dump_image rigol.bin 0x40000000 0x3FFFFFF
rigup scan rigol.bin > mso1074zs.txt
rigup license mso1074z.txt 0x1C0FF
On rigol:

if halt do not respond message, remove JTAG and re connect.
