; Start-up script for i.MX31 ADS board from Freescale

; J3 Power: 5VDC 5A + ---o)--- -
; S1 Power Switch -> ON
; J8 JTAG connector
; P1 4-16bit Alternate ETM connector - no >16bit support!
; P4 4-16bit Primary ETM connector - no >16bit support!

; --------------------------------------------------------------------------------
;    !!!    IMPORTANT    !!!  IMPORTANT    !!!
; Both ETM connectors deliver 5V on pin 14. This results in
; sending JTAG-signals with 5V-level, which could damage the cpu.
; Therefore do not connect JTAG via Mictor connectors. Do it as 
; mentioned above.
; Connecting both trace preprocessor and JTAG debug cable cause 
; signal issues on the JTAG signals. See readme file for recommended
; board modifications which solve this issue.
; Tracing is possible with maximum speed if the cpu board runs stand-alone.
; Limited tracing possible if cpu board is plugged onto the main board.
