kendryte-standalone-sdk | Standalone SDK for kendryte K210 | Machine Learning library

I am working on a project using the Kendryte K210 which is a 64-bit duel-core RISC-V machine. I am using the Kendryte GNU toolchain and the starting point was the Kendryte standalone SDK.

I am experiencing some frustrating core faults. The fault, a misaligned load, is happening after a balr to _Balloc in _ldtoa_r, where a ld instruction in _Balloc is attempting to load from an invalid address pointed to by one of the function argument registers (a0 in this case).

I have been trying to figure out when/where/how _Balloc and _ldtoa_r are used, but they are part of libc. My map file shows _ldtoa_r is somehow related to lib_a-ldtoa.o and lib_a-svfprintf.o and _Balloc is somehow related to lib_a-strtod.o and lib_a-mprec.o. I'm not sure because I am new to interpreting map files.

If anyone can help educate me on what _ldtoa_r and _Balloc are, how they are used, their relationship to these object files, and possibly how to properly interpret relevant lines in the map file, then I would be very grateful.

Thank you.
