* Import the nandwriter CCS project from writer\nand\evmc66xxl directory (in CCSv5, Project->Import Existing CCS/ CCE Eclipse Projects).
* Clean and build the nandwriter project.
* After the project build is completed, nandwriter_evm66xxl.out and nandwriter_evm66xxl.map will be generated under writer\nand\evmc66xxl\bin directory.
2. Uses Makefile to build nandwriter:
NOTE FOR BUILDING ON WINDOWS ENVIRONMENT:
For building on windows environment GNU utilities like "make" would be required.
The following build procedure should also work on MINGW-MSYS Bourne shell.
EEPROM Writer is a simple utility to program a CCS format image/data file to I2C EEPROM.
Steps to program the EEPROM with a CCS format data file (.out or .dat):
1. Be sure to set the boot mode dip switch to no boot/EMIF16 boot mode on the EVM.
2. Copy the CCS format data file to writer\eeprom\evmc66xxl\bin directory, and rename it to app.dat.
3. Change the file_name, bus_addr, start_addr and swap_data in writer\eeprom\evmc66xxl\bin\eepromwriter_input.txt if necessary. By default the EEPROM writer will load app.dat to DSP memory and write the data to I2C slave bus address 81 (0x51) at EEPROM device start byte address 0 with data swap disabled (0).4. Open CCSv5 and launch the evmc66xx emulator target configuration and connect to core 0.
5. Load the program writer\eeprom\evmc66xxl\bin\eepromwriter_evm66xxl.out to CCS, be sure evmc66xxl.gel is used in CCS and DDR is intialized.
1. Be sure IBL is programmed to I2C EEPROM bus address 0x51, if IBL is not programmed, refer to tools\boot_loader\ibl\doc\README.txt on how to program the IBL to EEPROM.
2. By default, IBL will boot a BBLOB image (Linux kernel) from NAND, to run this example, we need to change the NAND boot image format to ELF: a. In setConfig_c66xx_main() of tools\boot_loader\ibl\src\make\bin\i2cConfig.gel,
replace ibl.bootModes[1].u.nandBoot.bootFormat = ibl_BOOT_FORMAT_BBLOB;with ibl.bootModes[1].u.nandBoot.bootFormat = ibl_BOOT_FORMAT_ELF; b. Re-program the boot configuration table, refer to tools\boot_loader\ibl\doc\README.txt on how to program the boot configuration table to EEPROM.
3. Copy tools\boot_loader\examples\i2c\nand\evmc66xxl\bin\i2cnandboot_evm66xxl.out to tools\writer\nand\evmc66xxl\bin,rename it to app.bin and refer to tools\writer\nand\docs\README.txt on how to program he app.bin to NAND flash.
4. Once the programming is completed successfully, set the boot dip switches to I2C master mode,bus address 0x51 and boot parameter index to be 2.
5. After POR, IBL will boot the hello world image from NAND.
你好，请问这里的第四歩是什么意思？怎么操作那个set the boot dip switches to I2C master mode,bus address 0x51 and boot parameter index to be 2.，最后的boot parameter index to be 2.又怎么理解
