Am using iMX537 in my target board with Da9053 PMIC. PMIC is un-programed which will be generating default voltages without any Power-Sequence. When I am trying to program the iMX537 using Lauterbach Debug tool via JTAG , iMX537 is not getting programmed. JTAG has to scan 13 register's instead scanning only 5 register's. Due to this there is a failure in JTAG getting connected. Please let me know if anyone has faced the problem with JTAG and what are the ways to fix it. The iMX537 schematics is similar to the QSB schematics.
