AM3358 vs AM3352

Other Parts Discussed in Thread: AM3358, AM3352

Hi All,

I am in the process of bring up Linux 3.2 on my AM3352 based board.  I based the design on the EVM kit, which has an AM3358.  I have been chasing a kernel oops before the console is up.  I have narrowed it down to the arch/arm/mach-omap2/omap_hwmod_33xx_data.c file where the HW is being initilized in a call to a mmc3 init struct.

Question: Does the 3352 not have the same memory map as the am3358?  If so do I simply comment out the unnecessary hw inits, like the mmc3?  What else needs to change to support the subset of functionality that the 3352 has?

Thanks!

Chuck

    The difference between the AM3352 and AM3358 is the presence of the 3D Graphics acceleration core and Industrial Communication Subsystem core, PRU-ICSS, in the AM3358.

    AM3358 = AM3352 + 3D GFX + PRU-ICSS

    Are you perhaps using a different package option for the AM3352 (ie. 13x13) instead of the 15x15?

    Thank you...

    I am using the ZCZ package also... I commented out the init of the MMC2 and the board now boots to the login prompt!

    Thank you for the quick response.
