Dear Sandeep
In SPRZ294A.pdf “TMS320DM365 Digital Media System-on-Chip Silicon Errata (Silicon Revision 1.1) (Rev. A)” Page 7, It means the “Silicon Revision 1.1”can’t use Step2 method to organize other Nand flash different than shown in Table 2? What is your DM365 silicon revision you test 2GB MLC NAND?? ////////////////////////////////////////////////////////////////////////////////////////////////////// 2.1.1 Support for Big Block NAND Devices On DM365 Silicon Revision 1.1, the boot ROM code for NAND boot mode uses a table-based approach as well as a 4th-byte read approach to choose NAND device specifications in the following order: 1. Look for the NAND device ID in the table, and read the NAND device specifications. 2. If the NAND device ID is not found, then process the 4th Byte to read the NAND device specifications. Note: Step 2 assumes big Block NAND devices of size >= 256 MB and address cycles of 5. The table contains a fixed number of NAND device IDs and manufacturer IDs that are listed in Table 2. It also supports any other big block NAND devices not mentioned in Table 2. Table 2 lists the NAND device IDs supported by boot ROM code and their characteristics. Note: The current boot ROM code cannot support the NAND device IDs with specifications different than shown in Table 2. //////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Best regards Max Chou 周宏家 Inventec Besta Co..
