One of my tms-C6455 sometimes doesn't boot with i2 slave boot mode

Michael Markov

Hello, I'm using multiple dsp on own board, I'm programming their with i2c slave boot mode, for n dsp use n i2c interfaces, now number of dsps is 4.

Sometimes one of dsps do not receive i2c boot table (for each board this dsp is fixed).

Had somebody the same problem? How can I check functionality of this dsp (it is available from JTAG)

I have not seen this problem before. I doubt the I2C interface may not function well. Please double check the I2c clock and its interface. Also can you increase the i2c address delay to see if it makes any difference?

regards,

I'm not sure, but problem maybe was fixed by changing startup initialization. I cant say how (it had been done by hardware engenier), but it was used POWER_RESET connection to another reset/
