Unable to Program Flash: HX8K Breakout Board from Lattice

[Phi-sqrd]

Hi all,

I need help. I am new to the ice40 toolchain and have been using iceprog -S to program sram. However, I have learnt that iceprog without a flag does not program to flash. I have even tried running iceprog from apio upload -f or apio upload --flash, but that does not work.

Does anybody understand the issue or know how to solve the issue?

Many thanks
