Part Number:TMS320C5505
Hi,
I'm getting a custom PCB based on the TMS320C55x5 dsp stuck in a loop inside what appears to be the bootloader ROM. It appears to get stuck and then reboots every 6 seconds or so.
When connecting with the JTAG just before the 6 seconds period expires shows the program counter at this point :
I single-step a few lines ahead and then continue running the code, which boots correctly, but now its in emulation mode.
If I just boot without JTAG of the SPI FLASH memory it does the repeating stuck-loop and when I connect shows me same address FF6ADC when I connect with the JTAG. (I removed all GEL files to avoid any pre-configurations when using JTAG). The binary file signature of the file I flashed the memory starts with 0x09AA so I presume the bootloader in ROM will find the correct signature.
Not sure what could possibly cause this. Any suggestions would be welcome.
Cheers, Mike
