Folks, alas the pins VDD_OTP and VDD_USB are floating instead of being connected to VDD_EXT as recommended. The JTAG tests with my ICE1000 are ok. But when starting to debug, I get the error message "[TpsdkServer] Failed to halt processor 0".
Is the BF707 unusable or do I have to look for another explanation? Any ideas? Regards Klaus-Michael
I just found out, that the debugger is not able to recognize the BF707. I guess it tries to use the IDs stored in the unpowered OTP memory. Additionally, the Prozessor seems to stay in Reset. In the data sheet, there is a hint, that it checks all the power domains if they are within the specs before leaving the Reset state. Rouigh luck. I guess I have to throw the brand new boards in the waste....
If someone else, has other and more detailed info about my small problem, please hit the "Reply" bottom - Klaus-Michael
I´m afraid you will not be able to access the processor. As stated in the datasheet, under the Operating Conditions Table, VDD_OTP "Must remain powered (even if the associated function is not used)", whereas VDD_USB "If not used, connect to 1.8 V or 3.3 V".
