Exit code = 11... Device verify failure

Hi,

I use Jam STAPL Player Version 2.5 to implement CPLD upgrade.

But the program return "Exit code = 11... Device verify failure"

1. My system is ARM cpu on Embedded Linux.

2. I only change jam_jtag_io() to map our JTAG port.

3. The TCK click work about 5KHz

Suspicion:

1. The porgram can detect IC. I think that TCK, TDI and TDO are correct.

2. I use Quartus II program CPLD and then use Jam STAPL Player to do only verify action. The result is pass. Base on this experiment, the Jam STAPL Player verify function is correct.

So, The TCK, TDI and TDO are correct and verify function is correct. May the program is bad. But I do know how to debug the program function.

Below is my program message:
