Achievement unlocked: apparently posted enough about fpgas I'm getting email asking if I can hack into some board's fpga and recover the gateware.

(no, I can't. For one I don't know how, for two if I could I wouldn't take jobs from strangers that's got entrapment written all over it)

I can only assume that social media has trained us all to assume that volume of posting about a topic equals knowing about it, even if the posting is a large amount of saying I don't know stuff

@danderson depending on the FPGA (and board) the gateware might just be in an external SPI flash. But even if it is, it may be encrypted. (A bunch of modern FPGAs can auto-load gateware from SPI flash, and some of them internally decrypt it as they do so. Some FPGAs only have internal flash for the gateware; others need another MCU to spoon feed them gateware at startup.)
But yeah everything about “ask random person to recover Gateware” screams “Danger Will Robinson”.

@ewenmcneill I'm trying to not engage with the thing I'm definitely not going to be involved in, but it _seems_ in this case it might be more of a CPLD or something, where the config is all in-package. I'm sure there are viable avenues to get results, but I'm sure I don't know how to do it, and also just... no
