Our Custom #RustLang Target for #BL602 also needs "features" set to "+m,+a,+c,+f" ... Figured this out by comparing the Standard Rust Targets "riscv32imac-unknown-none-elf" and "riscv64gc-unknown-none-elf" (64-bit #RISCV, double-precision hardfloat)

Here's how we build #BL602 #RustLang programs with our Custom Target ... This also builds the Rust Core Library for our Custom Target

https://github.com/lupyuen/bl_iot_sdk/blob/rust/customer_app/sdk_app_rust/run.sh#L33-L77

Here's the Custom #RustLang Target for #BL602: "riscv32imacf-unknown-none-elf" ... We set "llvm-abiname" to "ilp32f" for Single-Precision Hardware Floating Point ... Similar to "gcc -mabi=ilp32f"

#RustLang runs OK on #BL602 IoT SDK ... After creating custom target "riscv32imacf-unknown-none-elf" yay! 🎉

Linking #RustLang code (riscv32imac) with #BL602 IoT SDK (RV32-ACFIMX) ... "Can't link soft-float modules with single-float modules" 🤔
