Description

Hi , i use the kc705_update branch to generate xc7k325 bit. the new bit chip_top.new.bit is same as chip_top.bit in beyondcompare.
And the command make bit-update which transfer to (data2mem -bm src/boot.mem -bd src/boot.mem -bt lowrisc-chip-imp/lowrisc-chip-imp.runs/impl_1/chip_top.bit -o b lowrisc-chip-imp/lowrisc-chip-imp.runs/impl_1/chip_top.new.bit ). the -bm and -bd parameter is same.
i look the data2mem instruction -bm filename Linkable Format (ELF) or memory (MEM) root file name with a .bmm extension is assumed. so i tried (data2mem -bm src/boot.bmm -bd src/boot.mem -bt lowrisc-chip-imp/lowrisc-chip-imp.runs/impl_1/chip_top.bit -o b lowrisc-chip-imp/lowrisc-chip-imp.runs/impl_1/chip_top.new.bit), but it dose not work either.

Research direction

Start with the kc705_update branch and the make bit-update target. Reproduce the data2mem command using src/boot.mem and then src/boot.bmm, comparing chip_top.bit with chip_top.new.bit as reported. Done means determining why the generated bitstreams are identical or why the alternate command fails, and documenting the verified result.
