C55 boot problem

metusa

I have problem with booting of C5505. I use C55BootImage.exe to create binary file. I select Secure/Encrypt Output option and click ReAuthor and bound to device. And my board does not boot. When I select Not bound to device option it works. I select key and seed values for both as follows;

-KEY : 0x100000000x00000100

-SEED_OFFSET : 0x00000000

-SEED : 0x2F71C554EEDF6500

I don't know why I fail for re author and bound to device option.

Best regards

This looks right. Which peripheral you use? You are using C5505 as you stated, correct?

I use spi, and 24bit spi eeprom for burning. Yes it is C5505. I have no problem for unsecure image, and also for Not bound to device options among the secure ones. I fail to use reauthor and bound to device option. I dont change the settings.

Thanks

This is correct. 24-bit SPI reauthorize and bound to device mode is not implemented because of secure ROM size limitation. Only the 16-bit mode is supported.

Sorry about the inconvenient. We are in the process to update the documents to make this clear.

Regards.

Thanks for replying. It seems I have two options. For bound to device option, how can I use the identifier key?

thanks

At user guide, I see device ID is 128bit (8 DevID register), but there are 64bit space in the boot image program. How can I use device ID?

Thanks

Only DIEID0-3 are used. If DIEID0 = 0x2023, ID1 = 0x0502, ID2 = 0x26B2, ID3 = 0x068D, the entry would be "0x20230502 0x26B2068D".

You have to read each device for their unique values.
