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

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...

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...
