Thanks, Anastasia,

Can you please explain this statement,

.printlock = SPI_PRETTYPRINT_STATUS_REGISTER_BP4_SRWD,

.unlock = SPI_DISABLE_BLOCKPROTECT_BP4_SRWD,

Looks like this is to support memory array protection. But it needs BP0-BP4.

Do I need to specify BP0 to BP3 as well?

Or I specify the setting when I initiate the flashrom programming command?

Regards,

Victor

Hello Victor,

Various feature bits are defined as macros in include/flash.h , some of them have comments explaining what they do. If the feature name is not descriptive, and there is no comment, but you think you might need this feature: feel free to ask. I would try to add comments later.

SPI_DISABLE_BLOCKPROTECT_BP4_SRWD and other unlock functions as in spi25_statusreg.c. Those functions have comments, hopefully this can help!

Thanks, Peter,

Where can I find the definition of terms like,

.feature_bits = FEATURE_WRSR_WREN | FEATURE_OTP | FEATURE_WRSR_EXT2,

SPI_DISABLE_BLOCKPROTECT_BP4_SRWD

Victor

Our "how to add a new chip" documentation should point you in the right direction: https://flashrom.org/contrib_howtos/how_to_add_new_chip.html

But feel free to ask further questions if anything there doesn't seem sufficient for your needs.
