I2C1 serial port on OMAP-L138

Deart E2E: 

Thank you for your help.

For some reason I can't get the I2C1_SCL running.

I use the following settings:

1. ICCNT = 0 for 65536 data count

2. ICMDR[10]=1 for the "Master"

3. ICMDR[9] = 1 for Transmit

4. ICEMDR[1] = 1 for “Ignore NACK"

5. ICPSC = 0x9 for I2C clock frequency = 80/10=8MHz (SYSCLK4=80MHz) 

6. I2C is enabled through the PSC1_11. PSC1_11 status register retunes 0x1E03 which means I2C1 is ON.

7. PINMUX4 = 0x22442244 - UART_TX/RX, I2C1_SDA/SCL, I2C0_SCL/SDA, GP1[6:7].

The seral port I2C0 works OK.

But I2C1 does not generate the SCL - looks dead.

Can you give me an idea what is going wrong?

Thank you for your help,
