<div> </div>
<div>1. Board is propeitery board</div>
<div>2. CPU: 8548 (e500 core, v2)</div>
<div>3. SDRAM is DDR2 (not DIMM)</div>
<div>4. DDR is working while using REG file (with JTAG loader).</div>
<div>5. DDR is *not*, working uboot.</div>
<div>6. Burn/Access FLASH is OK</div>
<div> L2-SRAM access is OK</div>
<div> TLB/LAW - triple check - OK</div>
<div> </div>
<div> Few trials so far: </div>
<div>1. using the "spd_sdram" to load the parameters,</div>
<div> while removing the "CFG_READ_SPD" and taking the parameters from teh REG file,</div>
<div> we get the WRITE ok, and the READ not </div>
<div> (using SCOPE to view the signals)</div>
<div>2. In all cases:<br> The D_INIT set in "sdram_cfg_2" *do not* fill the DRAM with <br> the known value of "sdram_data_init".</div>
<div> <br> Rather, after the DRAM is enabled, and we set D_INIT once again. </div>
<div> It fills the DRAM with the known value of "sdram_data_init".</div>
