This is what I got currently (mainline): U-Boot 2014.01-rc1-00165-ge03c76c (Dec 12 2013 - 09:26:20) I2C: ready DRAM: 128 MiB Enable d-cache DFU USB: VID = 0x 908, PID = 0x 2d2 NAND: 256 MiB MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 Net: cpsw So caches seem to be enabled, right? Or is i-cache still missing? Thanks, Stefan
