CC Debugger schematic + firmware

Hi Walter,

Both the schematics and firmware for CC debugger is already available online. You can find the schematics for the CC Debugger in the CC debugger User's guide (swru197), Section 10. The CC debugger firmware are included with e.g. the SmartRF Flash Programmer when you have installed it. (C:\Program Files\Texas Instruments\SmartRF Tools\Firmware).

Hope this helps!

Cheers,
ABO

Thank you! The problem is that the CC Debugger needs a bootloader that can flash the application. This bootloader must be programmed by an external programmer (i.e. SmartRF05EB). That means that I need a programmer anyway. It that right??

That's correct.

You will need a programmer such as e.g. SmartRF05EB or CC Debugger to program a blank SoC. When you have programmed the your CC debugger with the bootloader, you can program it over USB.

Cool, thank you very much!!!

Hi,

• The most up to date CC debugger firmware can be obtained by downloading and installing the latest smartRF flash programmer
• For information regarding updating CC debugger firmware, please refer to CC debugger user's guide,section 8.2

Manikanta,

Please verify that your hardware connection between the CC Debugger and your board is working. What board are you using?

Hi sir,

I was design a board with cc2545 chip .I was attaching the design file please verify that file let me know if there is a problem sir.

EFF-1702 VER1.0.pdf

I am connecting the cc debugger to the J9 connector which was in attached file.

Hi,

Looking at your design, it looks like you have connected your desing's 3.3V source to J9-9, so you may have a drive conflict with the CC debugger, which also supplies voltage to that pin. You should disconnect the signal between J9-2 [3.3V(D)] and J9-9 [3.3V from CC debugger].

Being that both should be 3.3V, I don't think it explains why you cannot detect the CC2545, but you should at least start with removing the drive conflict.

Hi,

In the attached schematics I don't how the cc2545 is connected to ground.

I do see the cc2592 ground pad is connected to ground through logical pin #17, however,

I don't see how the cc2545 ground pad is connected to a solid ground.

When cc254x ground pad is not connected, or not properly soldered to ground, funny things will happen.

Hi Sir,

Could you please share the connections or hardware setup

I will compare with your connection sir.

Regards,

Manikanta.k

hi sir,

I was checked the voltage across VDD,DCOUPL,RESET,RBIAS, are as follows:

VDD:3.3V

DCOUPL:1.86V

RBIAS:1.254V

RESET:3.3V

CC2545 section as follows:

Overall board:

Could you please share the process how the clock will activate through software.

Hi Manikanta,

The boards look good. I really cannot point out any potential problems here. Are you absolutely sure the debug signals are connected correctly? Your debug cable is not too long? Have you looked at the debug signals, including reset, (close to the CC2545) with an oscilloscope?

How to switch to the 32 MHz crystal oscillator is described in the CC2543/44/45 User Guide. It is typically also the first thing that is done in our SW examples.

Cheers,
Fredrik

hi sir,

I am sure that debug signals are connected properly sir.

After power on I was connected CC debugger as shown in the attached pic.

We observe the Debug signals and Reset signal in oscilloscope.(All are 3.3V)

we are not getting clock from crystal after power on the module. By this reason(clock from 32Mhz crystal) CC debugger may be  not detecting the chip.

As you said SW will generate clock in the before post.

How we can load the SW into the chip with out detection of CC debugger?

IS there any other possible way to load the SW ?.

Regards,

Manikanta.K

hi sir,

The first thing was no clock was oscillating at 26 and 27 pins of the chip.

As you said internal clock will handle the chip, how we can simulate that 16mhz clock?

how we can load the SW with out detection of CC debugger?

hi sir,

When am pressing the reset button on the cc debugger ,I could see voltage on the reset pin not completely falling to 0V level.

But when I press the reset button on my board there is voltage transition from 3.3v to 0v. Connections are verified from my board to cc debugger . If there is issue that chip is not going into reset by pressing the cc debugger(because of no complete transition from 3.3v to 0v) then the chip should go into reset when I press the reset on my pcb.

Hi Sir,

I was removed the R13 and short with a wire .

Now I connected the cc debugger it was detected the chip.

Up to now we got a issue on RESET signal.

He has already confirmed that he uses 1 nF (100 nF was a typo). Otherwise you would be correct:)

hi sir,

if I remove r10 ,the 3.3v and ground will be short when I press the reset button on my board sir.

hi sir,

I was connecting the two cc debuggers at the same time and to the same pc.

having same usb device id (0000) to the both debugger.

I am able to open the device control panel on one smart rf studio tool only .

I am not able to open device control panel on another smart rf studio tool.

the following window appears :

Is there any procedure to change the usb device id for the cc debugger.

or else how to connect the two boards to smart rf studio tool (one as tx and other as RX) at the same time to check the per test?

Regards,

Manikanta.K

Using 2 CC Debuggers with the same serial number will not work. You must change the device ID on one of them.

Hi sir,

I  interfaced the cc2592(power extender) to the I/O pins of cc2545 chip as following:

PA_EN -> P0_1

LNA_EN--> P0_0

HGM--->P2_0

I  connected the 2 boards to the PC with 2 cc debuggers to do the per test in smart rf studio tool.

The device Id's of cc debuggers as follows are 0000 and 8450

Initially I kept 0000 as TX and 8450 as RX .In this case communication was achieved

In vice versa case also communication was achieved.

My query was there is no option for selecting the range extender in Device control panel in smart rf studio tool.

But cc2592 was mounted on my 2 boards.

Could you please explain  how data transfer and reception is working without control of cc2592 chip which is in between CC2545 and Antenna.?

K.manikanta

It works because your boards will still radiated, and be able to pick up, some power. This is enough to maintain communication over very short range.

hi sir,

I need to keep one board as transmitter other as receiver permanently.

for this I done as follows as:

for receiver:

1) I kept the LNA_EN and HGM PIN in PA(CC2592) as high by connecting them to 3.3V. and PA _EN as low by connecting to GND.

for Transmitter:

1)I kept the PA_EN as high by connecting to the 3.3V and LNA_EN and HGM PIN as low by connecting to GND.

In this configurations Communication was not achieving.

Note: I done this connections in hardware.

hi sir,

Previously I said I interface the cc2592(power extender) to the gpio pins of cc2545 chip as following pins:

PA_EN    ->p0_1

LNA_EN ->p0_0

HGM ->p2_0

As I read Radio test output signals chapter in user manuals.

By using the OBSSELx registers (OBSSEL0-OBSSEL5) the user can output different signals from the RF

Core to GPIO pins. These signals can be useful for debugging of low level protocols or control of external

PA, LNA or switches. The control registers OBSSEL0-OBSSEL5 can be used to override the standard

GPIO behavior and output RF Core signals (rfc_obs_sig0, rfc_obs_sig1, and rfc_obs_sig2) on pins P1[5:0]

or P3[5:0]. For a list of available signals, see the description of RFC_OBS_CTRL0 register.

Could you please give brief explanation about these signals and RFC_OBS_CTRL0 register .

Is this mandatory to interface the cc2592 to the pins P1[5:0]

or P3[5:0]? or we can give to any gpio pins as I mentioned above of this post

if it is able to give any gpio pins. which values have to be placed in RFC_obs_ctrl registers?

If the documentation states that those are the only pins that can be used, that is actually the case. There is no way to change that.

Unless you are making a very simple transmit and receive without ack you must use the RF observation signals to control your PA/LNA.

hi sir,

There is no application note for interfacing the cc2592 to cc2545 chip.

I was given to the 3 gpio pins as said in the previous post.

I can't get you in the previous post. Could you please provide the solution for the following query:

1.can we connect the control signals of CC2592 power extender to the any 3 GPIO pins of CC2545. or not?

2.Please give the brief explanation about the RF observation signals sir?

Hi sir,

I interfaced to different pins.

Is there any solution to control the cc2592? without using rf observation signals.

or else I have to design a new board?

I was attached my design and board pics and cc2545 section in previous posts in this forum sir.

Please verify that documents and provide the solution sir.

Previously I was discussed in CC2545 AHDSP forum

please verify the following link:

https://e2e.ti.com/support/wireless_connectivity/f/964/t/450514#pi239031349=5

Hi sir,

I was confused with this CC2592 interface.

Can I use GPIO pins for just transmit and receive tasks or not?

Please give confirmation sir.

Or else I will modify and give it to the RF observation signals sir.

thank you sir  for your earlier reply.

Could you please give clarify on radio configurations in TX and RX.

IS there any document related radio configuration in TX and RX modes please share the document sir.

or else please share the steps have to be take in the TX and RX radio configurations.
