> why is this 2600? omap3 could do 3.3Mhz. > There is a silicon issue reported on TWL5030 which says that it can not operate at the stipulated highest frequency of 3.3MHz. The information I got is this: "I2C data hold time in HS mode is higher than specification when reading I2C registers. This leads to a data setup issue which introduces a frequency limitation in HS mode (can not reach 3.4MHz as specified in I2C standard). The limitation is for the Control I2C, and for SmartReflex I2C when using other products than OMAP34xx with SR. HS mode is working OK for SR I2C when using OMAP34xx." -- With regards, Jagadeesh Bhaskar P -------------------- Bugs are by far the largest and most successful class of entity, with nearly a million known species.
