how to download the lighthouse deck ?

Hi,

how to download the lighthouse deck ? My FPGA was burnt out, so I replaced it with a new FPGA and Flash chip

You likely only killed the FPGA, memories are much harder to burn, so I would suggest to solder back your memory which will get your deck up and running directly.

I haved tryed, but no start up, so use FT232H cable to download the memories ?

[justinleeyang]

Must use Lattice's HW-USB-2A or HW-USBN-2B programer to download the bin file ?

I haved download new fpga and spi flash, but crazyflie2.1 start up, report as following, why ?:

LHFL: Cannot communicate with lighthouse bootloader, aborting!
LH: FPGA not booted. Lighthouse disabled!

run successfully, thanks
