In the 2009 u-boot, i2c set speed is not implemented. There are provisions for architecture specific implementations but there are none relevant for the L138.

As a follow up, is there any way to test I2C 1 bus through uBoot? Michael B

MB 09:20 PM Software Development: uBoot I2C Speed Command [MityDSP L138]

Hi All,
I'm in the middle of debugging some I2C issues and was curious how the uBoot i2c speed command is handled. It seems to take/return Hz, does that relate to baud rate, bitrate, or just SCL frequency?
The i2c speed is defaulting... Michael B

MB 09:38 PM Software Development: Configuring OMAP-L138 peripherals from uBoot

Hi all,
I am interested in running a bare metal application on just the DSP core, and would like some help configuring as many of the peripherals (I2C, McASP, UART, DMA, etc.) from within uBoot instead of in the DSP code initialization.... Michael B
