Question about bootloader in "SPI SREC Bootloader Example Design for the Arty Evaluation Board"

Dear AVNET.

I have a question about your product.

* Product reference)

www.avnet.com/.../UG-AES-A7MB-7A35T-G-Arty-SREC-Bootloader-VIV2015-2-V1.pdf

"SPI SREC Bootloader Example Design for the Arty Evaluation Board"
"LIT# 5185-7A35T-Arty-SREC-Bootloader-VIV2015-2-V1"


Question #1)
In the above PDF datasheet at 10.2 (page 50), "10.2 Program the QSPI Flash Using the SDK".

Is the bootloader "SREC Bootloader" or "SREC SPI Bootloader" ?

In "9.3.4 Description of QSPI SREC Bootloader Source Code Edits". "SREC SPI Bootloader" is used.

But, In 10.2 (page 50), "10.2 Program the QSPI Flash Using the SDK", "SREC Bootloader" seems to be used.

Would let me know the bootloader at "10.2 (page 50)" whether it is "SREC Bootloader" or "SREC SPI Bootloader" ?


It is important for me.

I will really appreciate if I can be given answer.

Thank you very much.

Ick-Sung Choi.

    Hi, 

    Not that I'm knowledgeable on this platform, but it's the same thing I think? It's just terminology. You can call it whatever, it's still a bootloader that uses S-record format, decodes that, and programs the storage device over SPI.

    Thank you for your answer.
    The configuration flash is connected using SPI interface.
    And the "SREC Bootloader" uses BPI interface.
    It is the problem.
    Thank you.
