  • Forum Post: AM35xx Boot Modes. Suggested future options

    DaveB123
    I would like to confirm that Serial NOR or NAND FLASH are NOT a supported boot option. I ask because I realize the data sheet is still being finalized. If Serial NAND or NOR is NOT supported, I'd like to request that it be considered for future products. Related to this, I was wondering...

  • Forum Post: AM3715 Production PoP Programming

    Scott Huckaby
    We plan to use NAND flash as the booting image storage space. Once we begin mass production, must the NAND must be pre-programmed before it is put on the top of AM3715? Or may it be programmed once it is integrated with AM3715 on the board? Is this something we can expect a CM to do or should we find...

    I'm using an AM3517 Craneboard as a development platform for a future embedded design. I've successfully compiled X-loader and U-boot using the Craneboard git sources, which are based on TI PSP 03.00.01.06. From that compiled code, X-loader successfully runs U-boot, which in turn successfully...

    We're looking into increasing the memory performance of the am3517 and we're looking into using the file system partition of the nand flash as a linux swap partition. I was wondering if there are any concerns in doing this. How many read write cycles does the nand flash have? Is hardware wear...

    Narrowing down the potential problem causes; I've programmed the kernel and rootfs images to NAND from both U-Boot and from NFS-mounted userspace. Then in both cases, I dumped the images from NAND to RAM and did a CRC32 check (using U-Boot crc32 command). All tests passed, i.e. the images are written...

    VINOD STANLY
    What is the maximum NAND Flash supported on AM3356. Is there any limit on maximum Flash support. Datasheet mentions that AM3356 supports 1GB of Total Addressable Space.

  • Forum Post: Re: NAND Flash Support on AM3356

    Michael T
    VINOD: The 1 GB limitation does not apply since NAND is not memory mapped. It is accesed through a few registers in the GPMC register map. The NAND capacity will depend on ECC requirements. Regards, Michael T

    Also, the device ID does not completely specify the NAND geometry. Since NAND is ONFI compliant, ROM boot loader will not use the table of device IDs, but will use the Parameter Page info from NAND. Regards, Michael T
