Re: [U-Boot-Users] U-boot reset command on MPC8548CDS

Hi,

I have u-boot 1.1.6 running on my MPC8548CDS board. When trying the u-boot 'reset' command, the board hangs after RAM initialization. Stepping through the code showed, that the board hangs when accessing the DDR RAM during relocation. Accessing RAM isn't also possible with my BDI2000 in that state.

Is this a known issue? Why is the RAM not longer accessible after the 2nd initialization?

Does this happen with earlier versions of U-Boot? The reason I ask is that the I2C code for 85xx was recently changed (see fsl_i2c.c), and I2C is used to initialize DDR.
