Hello:

I'm now using the JN5168 , I used to enter program mode like(SPIMISO low -> RESET low -> RESET high ->SPIMISO high),and it always work.But just now ,I want to test the deep sleep function ,and after I downloaded a new firmware .I find that I can't enter the program mode anymore! When I operate RESET low and RESET high ,the device restart ,just like the SPIMISO pin doesn't work anymore

How can I reslove the problem,is there any other way to reprogram or erase the chip?
