Hi all I have two batch of boards with TMS320CV5509A dsps. The first batch is programming fine using JTAG and I can run the program just using JTAG (without external memory). In the second batch revision, for some reason i cannot get the Jtag to get working. It comes up with POWER Failure error as if it is having problem detecting power on the PCB. I have checked the PD line and it is g...

Jeff, If you are having problems with noise on long JTAG chains, try to buffer the JTAG lines. I have seen boards with 16 C6000 DSPs on a single chain that worked just fine. I guess the trick may be in keeping the JTAG lines well laid out on the PCB. If it is too

Hello everyone, I am still working on the schematic and layout for my first C55x board. I have included a Serial EEPROM attached to McBSP0, and a JTAG header on the board. I assume that in order to load my first board with firmware, I can use the JTAG port to control the DSP to program the Serial EEPROM over McBSP0. This is a C5506 design. So far, I've selected the ATMEL AT4...

All- I'm posting this question here, the global knowledge source for TI JTAG related issues :-) I have a batch of C5510A modules that are showing inconsistent JTAG scan test results. Out of 6, 3 are passing, two with buffered TCK and RTCK, and 1 without (without = bypass the buffer using zero-ohm Rs). The failing modules also are configured both ways. Due to this variation, I'm concerned...

Can anyone suggest how I might debug a non-working XDS510 Emulator when connected to my board? This is my first TMS320 design, and I placed a JTAG header on the board along with proper pull-ups and clock routing. The XDS510 is an inexpensive third-party design XDS510-USB2.0 model. The TARGET LED lights up in blue when my unpowered board is attached, but applying power to the bo...

I have run into a problem and I hope someone can help me out. I am working with a custom board that uses a 5509A DSP and an SPI EEPROM for code storage.I have successfully tested my software using the JTAG interface and now it is time to load the code onto the EEPROM. The problem it, I don't know how to program the chip through the JTAG. I have tried "FlashBurn" but it is only set up to program...

hi, guys in dsp group now, I'm working on C55x, and need to capture variable to PC realtime with Jtag for the purpose of debugging. For my system, there is no DSP/BIOS, so the RTDX can't work. I'm trying the Gel or Perl script to do this. Is it feasible? thanks for ur comments. my requirements: #1. no dsp/bios support, so, RTDX can't work #2 capture huge data from DSP target to PC fo...

Hi, Are you sure about the JTAG IR length and the number of Devices? If it is yes then there might be problem with your XDS510PP. Why don't you change the XDS510PP and try it. Also make sure you have installed the driver properly. Try res

Dan- Just a general comment, but why are you using CCS/JTAG for production testing? Do you have a simple HPI connector on your board? All of the full functional test groups we've worked with (Cisco, Sanmina, Nortel, etc) use HPI interface. JTAG tends to be slow, you hav

The JTAG port is used both for debugging software in development and for boundary scan hardware test in production. Most of the PLD vendors provide support in their programming software for other devices in the scan chain. But I have received mixed advice on putting TI DSPs in a scan chain

Hello I'm a bit confused about writing my own bootloader for the c55x (Probably C5510). I'm not sure what I need to use. I've found some simple send/receive examples in the CCS which uses RTDX that supposedly uses a JTAG interface. As far as I know, the JTAG interface is not a

Richard- Thanks for your reply. The last one, "in the board", was a good guess. The second one ("knee" glitch in TCK signal) we wrestled with during initial development of this module 3 years ago.

Hi, I am using CCS 3.3 and trying to connect my XDS510PP-Plus emulator. The emulator connection isgood, I verified it by running the SDConfig utility by Spectrum Digital. It can do emulator rest, verify and Test (it gives 2 JTAG devices connected). When I open the CCS and try to connect the device (Debug -> Connect), I get the following error. Can somebody tell me how to get rid

Hi folks, I'm just getting started with a custom board that I designed, based on the TMS320VC5506 DSP. I have a JTAG port on the board, and an XDS510 USB 2.0 emulator. I just installed Code Composer Studio 3.3, the demo, and during setup I could not find any GEL files for the c5506. Can anyone tell me what I'm supposed to do here? Do I make my own C5506.GEL file?

I am trying to run a small program using BIOS and a Simulator of 55xx platform (C55xx Rev3.0 CPU Cycle Accurate Simulator).I tried a small program that contains only a main() with a printf and a breakpoint. I also tried the example provided by TI (basic/clk.pjt).I changed the RTDX's field from JTAG to Simulator.The code compiles and starts running. But it gets stuck inside the function GBL_init. I...
