SPI flash bootloader protection #27

Open DurandA opened 3 years ago

Hi @gregdavill,

I just got my hands on OrangeCrab and am looking to use the internal SPI flash within a LiteX SoC to store the BIOS + firmware.

I was wondering if the r0.2 as sold by GroupGets has the W25Q128JVPIQ SPI flash preconfigured with block/sector lock in order to protect the first 4Mbits of the bootloader.

No, the flash hasn't been locked. That is probably something we should have done, but totally slipped my mind when setting up the production test suite.

When I update the boot-loader. Which we can setup as a .dfu update, I think it will likely unlock/lock those bits. To prevent accidental overwriting of that area.

Thanks for the answer. Feel free to close this issue or keep it open until you update the bootloader.

Btw, the board is awesome!
