Hello,
The expected sha256sum of the DOCA Bluefield OS image DOCA_2.0.2_BSP_4.0.2_Ubuntu_22.04-6.23-04.prod.bfb is 1ef541b1f28b1d1681a0541a6cd26e548e6336b84b66212ececa38c919b0cfaf, according to https://developer.nvidia.com/networking/doca.
However, an actual checksum is 66c426324db6477372414552ac9280001492fdcae7af13a5b036b2eecd66299b. I re-downloaded the image several times, but I got the same result.
Does this reproduce on your computer?
Thanks.
PS 1: You can try downloading the image from NVIDIA DOCA SDK | NVIDIA Developer > 2.0.2 > DOCA + BlueField OS Ubuntu Server 22.04 Image.
PS 2: I downloaded the image over HTTPS, so it is highly unlikely that a firewall or any other middleboxes modified the image.
