hi
i design a board with c6201 and want to load the program with xds510 jtag
emulator
what is the minimum requirement for jtag emulator to detect the IC? I mean
which pins have to be pulled up and what is nesessary for example oscilator
or reset pullup?
thanks
yasser

hi
thanks Dileepan. i saw that documents and as I underestand there is no need
for example to pullup the RSV pins or reset pin for the emulator to detect
the DSP.
furthermore in the datasheet of 6201 it is said that RSV pins are reserved
but said that they have to be pullup or pulldown as described there. Is that
nesessary? I mean what happened if somebody leave them unconnected?
thanks

Hello yasser,
For the 6201 DSP specifically - it is very important
to get the pullup/pulldown configurations correct. I
have seen incorrect 'reserved pin' configugurations
cause operational problems.
This was TI's first member of the c6x family and I
suspect that the 'reserved pins' are used for some
special factory test or analysis modes.
The following needs to be correct to 'get started'
debugging:
1. Reserved pins
2. power/ground
3. CPU clock
4. reset
5. JTAG connections - use pullups on EMU0/1

HI
thanks mike
unfotunately i design the board and the PCB produced and the chips are
implemented on the board and now the jtag emulator doesn't detect the board
i want to know is it possible that the RSV pins prevent the board to be
detected by the jtag emulator
i want to know the reason of that
thanks

Hello Yasser,
I have good news and bad news [hopefully not too bad].
The good news is that your JTAG scan path is working
properly - the bad news is that your 6201 is not
coming up in "emulation mode".
The key indicator
"The JTAG IR instruction scan-path length is 4 bits."
should show 8 bits instead of 4. There are two
possible causes that I am aware of [I hope that it is
#1]:
1. EMU0/1 [JTAG connector pins 13 & 14] are not pulled
up to 3.3v with a 10-20k ohm resistor. Ideally you
should check these with a scope - or, if you have some
'old fashion' wire lead resistors and some jumper
wires, you could connect connect resistors pin 5 -->
13 and pin 5 --> 14.
2. The reserved pins are not configured properly.
Let us know what happens.

hi
thanks mike
i did what you told me and found out lot of things
about the jtag
here the output of that commanns:
This utility is named `XDSPROBE'.
It is used to probe scan-controllers and scan-paths.
It uses Release-3 of the Unified-SCIF stack.
It is version `3.01.07'.
It is dated `Apr 10 2001'.
It is Copyright (c) 1990-2001 by Texas Instruments
Incorporated.
This utility has determined the operating system is
Win98.
---[Open the
controller]----
The IO port address 0x240 will be used.
Requesting Unified-SCIF to detect and open the
controller.
The controller has been detected and opened
successfully.
---[Perform the scan-path length test on the JTAG IR
and DR]----
Allocated 0x800 words of scan-controller memory, base
0x0
Changed the JTAG state to Test-Logic-Reset.
The test for the JTAG IR instruction scan-path length
succeeded.
The JTAG IR instruction scan-path length is 4 bits.
The many-ones plus many-zeros tested length was 4
bits.
The many-zeros plus many-ones tested length was 4
bits.
The test for the JTAG DR bypass scan-path length
succeeded.
The JTAG DR bypass scan-path length is 1 bits.
The many-ones plus many-zeros tested length was 1
bits.
The many-zeros plus many-ones tested length was 1
bits.
Freed all scan-controller memory.
The scan-path appears to consist of just one device.
The JTAG IR register for a single ARM7 or ARM9 device
has 4 bits.
The JTAG IR register for a single classic TI DSP
device has 8 bits.
The JTAG IR register for a single IceMaker TI DSP
device has 38 bits.
The JTAG IR register for a single C621x or C671x
device has 46 bits.
The older TI DSP devices with classic emulation
include the:
C4x, C5x, C8x, C20x, C24x products.
The newer TI DSP devices with classic emulation
include the:
VC33, C54x, C620x and C670x products.
The TI DSP devices with IceMaker emulation include
the:
C27x, C28x, C55x and C64x products.
If the scan-path consists of only TI DSP chips, TI ARM
cores
and TI micro-controllers, or 8-bit long bypassed
devices,
then the measured lengths indicate that both the
link-delay and scan-path are configured correctly.

I have good news and bad news [hopefully not too bad].
The good news is that your JTAG scan path is working
properly - the bad news is that your 6201 is not
coming up in "emulation mode".
The key indicator
"The JTAG IR instruction scan-path length is 4 bits."
should show 8 bits instead of 4. There are two
possible causes that I am aware of [I hope that it is
#1]:
1. EMU0/1 [JTAG connector pins 13 & 14] are not pulled
up to 3.3v with a 10-20k ohm resistor. Ideally you
should check these with a scope - or, if you have some
'old fashion' wire lead resistors and some jumper
wires, you could connect connect resistors pin 5 -->
13 and pin 5 --> 14.
2. The reserved pins are not configured properly.
Let us know what happens.

hi
thanks mike
i did what you told me and found out lot of things
about the jtag
here the output of that commanns:
This utility is named `XDSPROBE'.
It is used to probe scan-controllers and scan-paths.
It uses Release-3 of the Unified-SCIF stack.
It is version `3.01.07'.
It is dated `Apr 10 2001'.
It is Copyright (c) 1990-2001 by Texas Instruments
Incorporated.
This utility has determined the operating system is
Win98.
---[Open the
controller]----
The IO port address 0x240 will be used.
Requesting Unified-SCIF to detect and open the
controller.
The controller has been detected and opened
successfully.
---[Perform the scan-path length test on the JTAG IR
and DR]----
Allocated 0x800 words of scan-controller memory, base
0x0
Changed the JTAG state to Test-Logic-Reset.
The test for the JTAG IR instruction scan-path length
succeeded.
The JTAG IR instruction scan-path length is 4 bits.
The many-ones plus many-zeros tested length was 4
bits.
The many-zeros plus many-ones tested length was 4
bits.
The test for the JTAG DR bypass scan-path length
succeeded.
The JTAG DR bypass scan-path length is 1 bits.
The many-ones plus many-zeros tested length was 1
bits.
The many-zeros plus many-ones tested length was 1
bits.
Freed all scan-controller memory.
The scan-path appears to consist of just one device.
The JTAG IR register for a single ARM7 or ARM9 device
has 4 bits.
The JTAG IR register for a single classic TI DSP
device has 8 bits.
The JTAG IR register for a single IceMaker TI DSP
device has 38 bits.
The JTAG IR register for a single C621x or C671x
device has 46 bits.
The older TI DSP devices with classic emulation
include the:
C4x, C5x, C8x, C20x, C24x products.
The newer TI DSP devices with classic emulation
include the:
VC33, C54x, C620x and C670x products.
The TI DSP devices with IceMaker emulation include
the:
C27x, C28x, C55x and C64x products.
If the scan-path consists of only TI DSP chips, TI ARM
cores
and TI micro-controllers, or 8-bit long bypassed
devices,
then the measured lengths indicate that both the
link-delay and scan-path are configured correctly.
---[Perform the scan-path integrity test on the JTAG
IR]--------

---[Close the
controller]---
Requesting Unified-SCIF to close the controller.
The controller has been closed successfully.

Reply by ●October 26, 20052005-10-26
hi mike
thanks for very helpfull advices
i have pulled up EMU0/1 with 4.7k resistors now i changed the resistor to
20k and furthermore I see that there is ripple in the 3.3v i add capasitor
to the vcc and ripple decreased
nor that commands said that IR length is 8bit and DR length is 1 bit, what
is ur idea?
furtheremore after Isaw that the IR length is changed I start code composer
studio hopping that it detect the IC but it didn't and the current increases
about 100mA.
thanks
yasser

Yasser,
Some current increase while bring up CCS is normal - I
am not sure what the typical amount of current
increase might be.
I assume that you have configured CCS for a 620x
target device.
What error message do you get from CCS - I suspect
that it is "can't initialize target".
What is the configuration of yout 'boot mode pins'??

hi mike
yes the error message is what you said
Is the state of bootmode pins important for jtag emulation to start?
all of them are 0. I know that's not allowed but I didn't know that the
state of bootmode pins are important but I can change their state . what
state they have to be?
thannks alot

<mike>I have had trouble in the past with c6201
devices when the pins were configured for 'host boot'.
I would suggest that you start with 00101 [no boot,
map1]. If you are still having trouble with CCS
coming up, apply a hardware reset [I hope that you
have a reset button] and keep it applied. Open CCS
and when you see the 'splash screen', let it go. Try
it a few times to see if it helps.

<mike> Anytime that you are making connections to a
device, ALWAYS select a 'legal' configuration. If the
documentation says that something is reserved or
illegal then "do not do it". BTW, 00000 is a legal
configuration.
