28. If the configuration is correct, the user may click the “Continue” button in the form

shown in Figure 2-8: “Warning Message Before Generating The Keys”and

generate the files.

29. Once the generation is complete, you will get a pop up window as shown in Fig-

ure 2-9: “Efuse File Generation Completion Message”.

30. The output binary and hex file will be generated and stored in the out_binaries

directory.

31. The output file names are fixed. These are otp_efuse.bin, efuse_data.h and

otp_efuse.hex.

32. If the programmer requires a header file to compile with the environment, the

efuse_data.h header file may be used as the input. Please refer to step 3.

33. If any JTAG programmer is used to program the board, then otp_efuse.hex or

otp_efuse.bin file will be used as the input, depending on the tool requirements.

The start address of JTAG download code should be 0xE0000. Once your Efuse

download is completed, write 0xE0349 to address 0x40002738 to the reset han-

dler address itself, to launch the downloaded code.
