Problem Title:
Virtex JTAG - XAPP139 has a misprint on shutdown sequence for AGHIGH command
Problem Description:
Urgency: HOT
Problem Description:
XAPP139 has a misprint on shutdown sequence. The value of the AGHIGH
command is incorrect. This is step 7 on page 10 of XAPP139
Solution 1:
Page10 of the XAPP139 application note
( http://support.xilinx.com/xapp/xapp139.pdf ) has a typo in the
shutdown sequence.
What we have in the app. note is this:
0011 0000 0000 0000 1000 0000 0000 0001
-> Header: Write to CMD
0000 0000 0000 0000 0000 0000 0000 0100
-> AGHIGH command asserts GHIGH
The AGHIGH command is actually 1000, not 0100.
So the second 32-bit word should be:
0000 0000 0000 0000 0000 0000 0000 1000
