Hello,
I'm working with a custom board with 2 C6657 DSP. I would like DSP1 to boot DSP2 via I2C. I configure DSP2's boot strapped pins in I2C passive mode.
I then follow the instructions from sprugy5c.pdf, page 33 " Loading Image Into a Slave Device" and run a progrm on DSP1 that does the following:
1- send 6 data bytes:
length = 6 bytes
checksum = 0 (disabled)
mode = 41 (I2C slave)
2 send the boot table, which is the DSP2 program converted with the hex conversion utiliy.
Unfortunately the DSP2 program doesn't seem to run.
Are the steps I'm following correct? Am I missing any?
Is there an example of booting with I2C in passive mode?
Regards,
Emilie
