OMAP-L138 ARM config the EMIFA

Other Parts Discussed in Thread: OMAP-L138, AM1808

1. I have an OMAP-L138 EVm board.

2. The board has CCS project for DSP side. From the DSP side, I can setup the EMIFA using the following code,

   EVMOMAPL138_lpscTransition(PSC0, DOMAIN0, LPSC_EMIFA, PSC_ENABLE);

   EVMOMAPL138_pinmuxConfig(PINMUX_EMIFA_NOR_REG_0, PINMUX_EMIFA_NOR_MASK_0, PINMUX_EMIFA_NOR_VAL_0);

   ...

   EVMOMAPL138_pinmuxConfig(PINMUX_EMIFA_NOR_REG_7, PINMUX_EMIFA_NOR_MASK_7, PINMUX_EMIFA_NOR_VAL_7);

3. In the ARM side, since I don't have sample for OMAP, I am using the following code to do the same thing, (got the bsl from AM1808 ARM code)

   EVMAM1808_lpscTransition(PSC0, DOMAIN0, LPSC_EMIFA, PSC_ENABLE);

   EVMAM1808_pinmuxConfig(PINMUX_EMIFA_NOR_REG_0, PINMUX_EMIFA_NOR_MASK_0, PINMUX_EMIFA_NOR_VAL_0);

...

   EVMAM1808_pinmuxConfig(PINMUX_EMIFA_NOR_REG_7, PINMUX_EMIFA_NOR_MASK_7, PINMUX_EMIFA_NOR_VAL_7);

BUT it failed, I can't change the SYSCFG value from ARM side.
Both side, the SYSCFG address are same, 0x01C14000.
Any idea? Do I miss any register to enable?

Does gel cause any trouble?

    What revision of the silicon are you using? Version 1.1 and earlier require the KICK registers to be unlocked. The board GEL file performs this function on connecting (DEVICE_kickUnlock()) so try using that to see if it helps.
