Does anybody tested code for Freescale with fixed memory on real hardware? It seems that the code does not initialize a lot of registers (for example DDR_WRLVL_CNTL_2 and others) in function fixed_sdram(). But it does this in function fsl_ddr_sdram() which i scalled if we have DIMMs. Currently my u-boot hangs while testing upper regions of memory. PS. I have tested the memory with Freescale's proprietary tests (called DDR Validation) that use USBTAP and the test shows OK. Can anybody give me a suggestion? Thank you. --- Vitaly
