Now we are debugging boot of LS1020.
Chosen two single end@100M as SYSCLK and DDRCLK, the Boot is ok.
And want to use one Differential Clock@100M ,while use 4.7K resistor to pull IFC_WE0_B（cfg_eng_use0）down to GND. But LS1020 can not boot up.
Pls check the configu as below and the PBL in attached, and give some advise how to boot with Differential clock,TKs!
