LFS Configuration - Invalid Cache Size

[JeffWelder]

Hi, I appreciate the writeup on mounting a binary file. The OFSMount utillity works great.

I however am running into an issue with setting up the Explorer.

Here is the configuration of my LFS onto an 8MB flash chip.
.read_size = 256, .prog_size = 256, .block_size = 1024 * 4, .block_count = 2048, .cache_size = 256, .lookahead_size = 512, // must be multiple of 32 .block_cycles = 1000, //Highly suggested to set block_cycles in the range of 100-1000.

I think my configuration is valid, but please let me know if I am missing something.
Thanks,
Jeff

May be you can make project opensource?
tool is great, but you don't work with it.
