Booting linux problem with mDDR clock at 150MHz

Other Parts Discussed in Thread: AM1808, OMAPL138, DA8XX

Hi, I am working with EVM AM1808 , it work well with linux and the mDDR clock is 150MHz.

We have a custom board with the same mDDR and OMAPL138.

If the mDDR clock is 140MHz (SYSCLK1 of PLL1 at 280MHz) the board work well with U-Boot and Linux .

If the mDDR clock is 150MHz (SYSCLK1 of PLL1 at 300MHz) the board work well with U-Boot but Linux does't boot !!!!!

I have checked the time parameter (SDTIMR1,SDTIMR2 registers) and all is goods. With the same value on EVM all is OK.

Can you help me ?

    Hi,
    Can you please attach the complete bootup log for the both working and non-working boot (150MHz) ?
    Please try to tune the drive strength of mDDR and check.

    Hi,

    I have tested the four combination of strength but at 140 Mhz full strength and 3/4 strength works well ; at 150MHz all combination of strength doesn't work.

    This is the log at 140MHz OK:

    Could be it a board lay-out problem ?

    In our board we use on mDDR data bus 22 ohm resistor, could we change this value ?

    Hi,
    I have tested the four combination of strngth configuration but the problem is the same: full strength and 3/4 strength at 140Mhz work well ; all combination of strength at 150Mhz doesn't work.
    This is the log with mDDR at 140 Mhz OK:

    Could be it a board lay-out problem ?
    Could we change the bus data resistor ? (now we have 22 ohm how as EVM AM1808)

    Hi,
    I have tested the four combination of strngth configuration but the problem is the same: full strength and 3/4 strength at 140Mhz work well ; all combination of strength at 150Mhz doesn't work.

    Could be it a board lay-out problem ?
    Could we change the bus data resistor ? (now we have 22 ohm how as EVM AM1808)
