I2C initialization error in HPI boot driver

Ajanta Sarma
Prodigy 10 points


Hi all,

I am using TI6486 multicore DSP. This problem is regarding I2C interface. I am initializing I2C and UART in core 4 and have opened an instance in each core (core 0 to core 3). 

When I try to configure IP parameters via DSP UART (minicom) , I2C bus gets hanged in EEPROM write. However, the whole function works perfectly when I boot DSP through JTAG. I am facing the problem whenever I am booting DSP via HPI.

    Hi Ajanta,

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com). 

    For DSP HPI booting, please refer section 4.3.2 HPI Boot Mode from boot loader user guide. .

    Thank you.
