Boot linux in fpga(without firesim), where should I put the filesystem?

[Dean You]

Hi all,

Our group is going to boot linux in a Large-scale accelerator(without firesim support).

We tried to input the source code of u280, but we found that the interface of blockdev was different from what we expected (we initially thought that it was placed on the SD card and should have an SPI interface, but we did not find it in the interface of blockdev).

If we use the u280 code, where should we put the file system? 

Or do we need to modify the source code? I found that vcu118 can generate spi interface.

Is this solution feasible? Do I need to regenerate linux binary and img?

Best regards,
Dean
