RTOS/TMDSICE3359: Clock synthesizer problem

Dear E2E Community members.

In TI-RTOS 04.02.00.09, I am trying to run a demonstration program NIMU_FtpExample_icev2AM335x_armExampleproject.

When it starts, "Clock synthesizer: Read: Failed, Clock synthesizer: Write: Failed" is displayed and RMII PHY clock can not be supplied.

Observing the I2C write, the address is being output, but data is not output.

(See attached figure)

I expect 0x65 as the I2C address, but 0x71 seems to be transmitted.

Hi,

The example should work as is. Do you have another board to try? and have you also tried NIMU_BasicExample_icev2AM335x_armExampleproject? Or recent PRSDK 4.3 - software-dl.ti.com/.../index_FDS.html ?

Regards,
Garrett

I chased in I2C_drv.c using debugger.
I noticed what I was saying going into the process of 10 bit address mode of I2C.
At the beginning of the function ClockSynthesizerSetup () in main_icev2AM335x.c, variable i2cTransaction was cleared to zero.
As a result, it seems to be solved.

Thanks.
