Hi Cduced,
This is a lower cost 10G card that has a flash size that is half the size of most of our other cards. Because of this there is no room in the eeprom to have two images in flash (which is required when doing a failsafe burn).
MLNX_OFED installation is using the mlxfwmanager tool which is located at the firmware directory, this tool doesn't support burning non-failsafe images so this explains why the tool couldn't burn the new firmware on the card.you can overcome with the following, 1. download the relevent bin file ( according to the NIC psid) from:Firmware for ConnectX®-3 EN - Mellanox Technologies2. burn the new firmware (using the --nofs switch): 1. mst start2. flint -d mlx4_0 -i fw-ConnectX3-rel-2_31_5050-MCX311A-XCA_Ax-FlexBoot-3.4.225_ETH.bin --nofs burn
