As I mentioned in some threads, we are trying on MX6Q+LPDDR2 combined design. but make no sense why boot failure in mfg bootimage.

We use Mx6DQSDL LPDDR2 Script Aid V0.04.xlsx to generate flashheader DCD part (attached file 6q_lpddr2_32.inc). The Samsung eMCP

DS attched,too.

Our DDR config:

Single Channel 32bit

2CS, each cs is 128Mx32 (totally 1GB)

With default DSE 40ohm (SI configuration in Mx6DQSDL LPDDR2 Script Aid V0.04.xlsx ), 400MHz DDR stress test failure, but it's okay change them

to 34ohm. But with this stress pass DCD, my uboot_mfg can't boot properly (no output in default console).

Please help us!
