OMAP-L138: I2C driver

Part Number: OMAP-L138

Hi,

I am having an issue with TI I2C driver , the driver gets stuck at code,

"while(I2CMasterIntStatusEx(hwAttrs->baseAddr,
I2C_INT_ADRR_READY_ACESS) == 0U) {
}"

looks like it is unable to get the access for registers forever.

I only have one I2C slave device connected.

Resetting the processor is not helping too, only works sometimes.

What could be the cause for this to happen?

Thanks,

Kushal

Hello Kushal,

I'm sorry, but TI has stopped supporting PDK based (TI-RTOS or bare-metal) SW development for OMAP-L138. Please refer to this announcement and find consolidated resources there.

Hi Jianzhong,

I added a delay after each transaction and this was able to solve the issue, but didn't actually understand why this was happening, as the API "I2C_transfer" was returning true indicating successful transfer.

Thanks,

Kushal
