5. ECC Operation Menu

jcan

1. DataDecryption:

*Supports customXOR keys.

*The page size xblock size of the custom key needs to be divisible by the block size of thecurrent image.

* Only custom XORkeys with fixed content are supported.

*The problem of thebuilt-in XOR key not being able to perform XOR or not performing a complete XORcan be solved by using a custom key.

2. Cut bytes/bit

1. The bitmapportion can be automatically cut, and the page can be cut by holding down Ctrland left-clicking.

2. Cut one byte ata time. After cutting, the correctness of the cutting can be determined bychecking the ECC.

3. Alternatively,you can directly copy the cut results from other software into thecorresponding PLANE editing box.

4. The cut bit ismainly for FC main controllers.

5. With increasedmagnification, the guide lines also become larger, making it less likely tocause eye strain.

6. Bytes and bitscan be mixed and cut.

3. ECC merging andECC amendment

1. ECC mergecorrection uses the reread command to read multiple times, merges and repairsDUMPs in different states, and generates the best results (merge correctiononly corrects the current master dump).

2. To merge andcorrect, you need to select an image file with the exact same structure as themain image and only correct the ECC of the main image.

3. ECC correctiondirectly corrects the currently opened dump.

4. Both mergecorrection and correction can be performed by entering the starting page numberor different mirror numbers to correct certain specified positions.

4. Reread Test

1. Open the filecontaining the stored parameters and perform the test according to theparameters stored in the file. (Data is in 16-byte groups; match the currentcommand. The parameters can be defined arbitrarily.)

2. Devices withvoltage regulation can select the voltage setting option, and the power supplymode can be selected from two different modes: 0x0024 and 0x80ac.

3. After selectingthe reread command, the corresponding address parameters will be displayed inthe address parameter bar below. You can modify the address parameters bychecking the box.

4. After selectingthe reread command, the corresponding data parameters will be displayed in thedata parameter bar below. You can modify the data parameters by checking thebox.

5. Parametersearch: After selecting a command, the algorithm will select and retain therelatively better parameters corresponding to the current command.

6. Reread test:Reread the chip based on the current command and address. The results aredisplayed directly in the map.

(In the map, onesquare = 1 sector (512 bytes), green = no error, red = error, black = FF, white= 00).

7. Read ONFI orJEDEC parameters. If the current chip supports this, it will list the chip'sdetailed internal parameters.

8. Supports customcommand parameters. (Note that there are risks involved; do not customizeparameters without full understanding.)

9. The cumulativecount refers to the number of times the current test loop is performed.

a. Other settingsrefer to the chip read settings.

5. View the imageusing bitmap

You can retrievethe bitmap at any step to view the image after processing in the current step.

6. Check theservice area

1. Step setting:The step setting indicates how many sectors are displayed in the left row.

2. Address:Entering the sector number will jump directly to the current address, anddragging the scroll bar will also change the current address.

3. Right-clickingallows you to add tags, which will then appear in the lower right corner of thescreen. This makes it easy to navigate to different sections.
