Emlink ICE for Blackfin Connections
Q: How to connect the Emlink to my target board?
A: Emlink has two sides, one is connected to PC through an USB port(Host), another
is JTAG port to connect to your target board’s JTAG port. Emlink can be power supplied
via PC’s USB port.
Because of the Emlink JTAG port is 20pins, 2.54mm female interface, it can be easy
to plug it into the target’s JTAG 20pins directly (notes that the JTAG signal should be
designed following Emlink Signal described in the hardware documentation. Meanwhile,
Emlink can also connect to JTAG 14pins, 2.54mm interface, which designed following
ADI EE-68 used, in this instance, Emlink first to connect with a convert module (a tiny
board), Pin1 to Pin1(red triangle):
Figure 3.1 Emlink + JTAG20-14-8 convert module
Q: How to confirm the Emlink connection? Why errors appeared?
A: Emlink does not support ADI VisualDSP++ ‘ICE Test’ function to test the ICE
connection. Emlink will work normally in these circumstance:
* there is seem ‘USB Serial Coverter A and B’ under the ‘General Bus Controller’,
while running the Device manager, or
* connect to the target through VDSP++ Session and no errors appeared.
Emlink for VisualDSP++ also gives two type of errors to test the connections(same
as ICE TEST function):
(a) “Emlink not Found” (b) “Proccessor not Found”
Emlink have not connect to PC,
or Emlink USB driver install failed,
or Emlink ICE has broken.
The target board have not power up,
or JTAG ports do not connect well,
or JTAG signals mismatch as described,
or something wrong with target board,
such as no enough voltage and current.

Emlink for VDSP++ Driver Installation
A webpage will be prompted out after input the Emlink CD to your CDROM (Enable
Win-Autorun), then click to ‘Install EmlinkforVDSP++’ on the right side:
* If disable the Windows Autorun function, please find this file and click to run:
‘AutoRUN\index.htm’.
* Any windows system cautions appeared while installing, please click OK.
Here click EmlinkforVDSP++.exe to run and settings as following:
1. Check which version of VisualDSP++ has installed on your Windows. Emlink driver
setup file can detect any one or more version of VisualDSP++, the check box can be
selected if any version of 4.5/4.0/5.0 being installed on your PC, otherwise it is a gray
check box. (ADI VisualDSP++ should be authorized by ADI.)
Figure 4.2 Choose which version of VisualDSP++ (one or more)

2. If one or more version of VisualDSP++ can be select, click ‘Install’ to continue, the
prompt out window as following:
After a while, the Emlink USB driver should be installed to your windows, and display
message such as: ‘…Process completed.’, then press Enter to finish, show as figure
5.2(a). The setup program will go on to copy and install Emlink driver for VDSP++. If the
last message gives out: ‘Completed’, installation has success and finish, show as figure
5.2(b).
Figure 5.2 (a) press Enter to exit USB installation (b) install completed and all 100%
3. Create a new Session under VisualDSP++ 4.5/4.0/5 to check if the
EmlinkforVDSP++.exe installed success or not. If the installation was correct, the
reserved device ‘Legacy target’ was available (can be selected) as following.
Otherwise, the ‘Legacy target’ could not be selected (gray) if the Emlink driver install
failed.
Figure 5.3 (a)Emlink target selection for VDSP++ Session (b)Emlink device
NOTES: If the Emlink USB driver installed failed, the error ‘0x80004005’ will be
appeared while connect Emlink to your target. Please check them like Figure 5.3.

Emlink for VDSP++ Screen Shots and FAQs
☼Emlink driver for VisualDSP++ setup process is easy to understand: click EmlinkforVDSP++.exe to run,
then the driver could be installed on the Windows system, the ‘Legacy target’ should be available to select.
Figure 6.1 Emlink for VDSP++ Connection Type
☼Emlink ICE for Blackfin can use to debug BF531/2/3/4/6/7 target: debug source code in RAM or trace in
Flash.

Hardware signals and ports
Emlink has two sides, one is connected to PC through an USB port(Host), another is
JTAG port to connect to your target board’s JTAG port. Emlink can be power supplied via
PC’s USB port.
Figure 7.2 Emlink JTAG signal definition and connection
NOTES for JTAG signal designed:
- It is recommended to design your target board as 20pins, then Emlink
can be plugged in directly.
- If designed to other pins (only connect the active signals’ pin), then
user has to connect correct signal to Emlink JTAG port.
- There is 10Kohm resistor pulled up inside Emlink nTRST pin, please do
not pulled down with resistor this signal in board side (open or >10Kohm).
- All signal ‘GND’ should be connect to target board ground, 0V.

Signal Type Description
TRST Input
Asynchronous
Test Reset (JTAG): Resets the test state machine. The TRST signal must be
asserted after power up to ensure proper JTAG operation. The TRST signal has a
10 Kohm internal pull-up resistor. Please do not pulled down with resistor on
this pin in board side, but let it open or pulled download >10Kohm.
TCK Input Test Clock (JTAG): Provides an asynchronous clock for JTAG boundary scan.
TDI Input Test Data Input (JTAG): A serial data input of the boundary scan path. This
signal has a 10 kW internal pull-up resistor.
TDO Output Test Data Output (JTAG): A serial data output of the boundary scan path.
TMS Input Test Mode Select (JTAG): Controls the test state machine. This signal has a
10 kW internal pull-up resistor.
nSRST Input The target system reset signal. ICE can reset target via this signal.
NC X No connect on Emlink side.
GND X Ground.
RES X Reserved.
Refer to the IEEE 1149.1 JTAG specification for detailed information on the JTAG
interface. This document assumes a working knowledge of the JTAG specification.
Power supply
Emlink can be power supplied via PC USB, without any power adapter.
Emlink Connect Target
Figure 8.1 (a)Emlink target selection for VDSP++ Session (b)Emlink device
NOTES: If the Emlink USB driver installed failed, the error ‘0x80004005’ will be
appeared while connect Emlink to your target. Please check and resolve by:
* check if there is ‘USB Serial Coverter A/B’ device under the list. if there is ? or ! on
them, please re-install EmlinkforVDSP++.exe again, and restart your windows once
after finished the installation, until there is no ‘?’ or ‘!’ on them. And the correct status of
these device show as figure 8.1(b).
