Sample NAND Secondary Boot from tech document spraag0d

I tried the same job with a smaller AIS which uses only 4 blocks.
And the result is correct.
Read timeout will only be occurred when reading 9th page of 5th block from the first block i wrote.
Once the timeout occurred, the all pages after it will read timeout too.

Do anyone have experience like this?

Thank you.

Hi, Anders

 I tried the same job on DM6437 nand boot. My problems are very similar to yours.So I wish you could give some advice.

1.Have you boot from nand flash successful?Can you consistent boot 6437 from nand flash without secondary boot?

2.Where do you burn nandboot.ais to? eeprom or nand flash ?The file you write into nand flash by NANDWriter projec is *.bin or *.ais?

3.Which bootloader version you used? 1.3 or other?in the doc SPRAAG0d it is said"NAND flash boot is fully supported on Rev 1.30 of the device,For Rev 1.0 and Rev 1.20 this boot mode was supported thru secondary boot only"

4.If the NAND bootmode must use FASTBOOT?

5. How do I burn the nand flash? use NANDWriter project or FlashBurn?

thanks a lot

1.Have you boot from nand flash successful?Can you consistent boot 6437 from nand flash without secondary boot?

Yes, I can boot from nand w/o 2nd boot.

2.Where do you burn nandboot.ais to? eeprom or nand flash ?The file you write into nand flash by NANDWriter projec is *.bin or *.ais? 

Write *.bin to nand flash.

3.Which bootloader version you used? 1.3 or other?in the doc SPRAAG0d it is said"NAND flash boot is fully supported on Rev 1.30 of the device,For Rev 1.0 and Rev 1.20 this boot mode was supported thru secondary boot only"

I'm not sure about my bootloader version. How can I find it?

4.If the NAND bootmode must use FASTBOOT?

I tried FASTBOOT only. Document says the both modes work.

5. How do I burn the nand flash? use NANDWriter project or FlashBurn?

use NANDWriter.

Hi, Anders

Thank you very much! your suggestion is very helpful

Write *.bin to nand flash.

 Do both nand bootloader code and application code need to be converted to .bin?    How do you convert *.out to *.bin? by genAIS.pl which is from spraag0d?  nand bootloader code and application code are in one .bin file or several different .bin files when being burn to nand flash?

 I don't kown how to find the bootloader version too. In spraag0d we can find the words "The bootloader version can be found by reading the ROM location 0x0101A00." But I can't find bootloader version like this by CCS. Where do you get your nand bootloader? I use the \Sample NAND Secondary Boot\NAND Secondary Boot\nandboot\nandboot.prj which is from spraag0d.zip downloaded in ti.com and convert  *.out to *.bin. Then write *.bin into nand flash by NANDWriter project. But failed.

Thanks for your answer again.

yes, i convert OUT to BIN by genAIS.pl.
if you want to use 2nd bootloader, they should be two different BIN files.

nand boot : 
    convert nandboot.out with nand boot mode, write it to 1st block of nand flash.
    And write app.bin from other block.

eeprom(i2c) boot :
    convert nandboot.out with eeprom mode, write it to eeprom by I2CWriter.
    And write app.bin to nand flash.

just remember to set the right  "blockNum = START_BLOCK_NUM;" in nandBoot.c which is the start block of app.bin.
I tried nand boot and successed, and have not tried eeprom boot yet, it is just in theory. ^^

i am converting my *.out to *.bin using genAIS.pl..

can anyone tell me the problem with this utility?

another question is it possible to boot nand flash?? directly using NANDWriter project???
