  • Forum Post: Re: Debug boot firmware

    Bernie Thompson TI
    Unfortunately the source code to the ROM boot loader is not available (this applies to most other OMAP/Davinci/C6x devices as well). In the case of the OMAP3 the primary source for information on the ROM boot loader is SPRUFD6 , which does not go to the level of entry/exit points but does detail how...

  • Forum Post: Re: OMAPL137 SecureDigital versus NAND/NOR Flash?

    Joe Coombs
    Chikku, When booting from a 16-bit NOR device, you don't need to worry about special EMIFA connections for the initial 8-bit read. Just connect the NOR device to EMIFA (chip select 2) in the standard 16-bit way. The initial read will only look at the lower 8 bits of the first NOR word, but that...

    Joe Coombs
    Chikku, Sorry, I may have misstated what happens with the first NOR word. The bootloader will read the lowest 8 bits first to determine whether to operate in 8- or 16-bit mode. Then, it will read the rest of the first word before continuing on to the rest of the NOR contents. Also, the wiki page...

    Misha, Mariana, The boot loader does not implement using a GPIO as the CE for the NAND, and therefore booting from NAND devices that require the CE to be low during the entire tR time is not supported. Regards, Daniel

    I want to have a boot sequence on OMAP-3530 that includes UART3, MMC1, and NAND, with NAND the last of the three. SYS.BOOT[5:0] = 0b101111 = 0x2f looks from table 25-4 in spruf98d (3530 Technical Reference Manual) like it would do just fine. However, using my Rev.G OMAP-35x EVM it doesn't seem to...

    Thanks Jeff, I'm using the OMAP L137. I agree that D800K003 is targetted at the DSP. So the DSP will execute the commands dictated by the AIS script. But AISGen for D800K003 now appear to give the option to jump on either the DSP or the ARM next (it wasn't an option with D800K001). So I assume...
