The purpose of this Hg tree (derived from leo2moko-debug) is to facilitate an attempt at reconstructing an L1 source that would match the binary object version we got with our TCS211 semi-src delivery from Sotovik. The source tree contained herein does NOT compile all the way into a complete firmware image, instead the link step currently fails because most L1 modules have been replaced with dummies. The purpose of this tree is not to produce a complete fw image, but to facilitate compilation of individual C modules pulled from the LoCosto L1 source in the TCS211 environment. The envisioned mode of usage is as follows: 1. Choose an individual L1 C module to work on. 2. Copy the source for the chosen module from the LoCosto source in the place of the dummy in this tree. 3. Run ./winebuild.sh in the g23m directory and examine the output in report.txt. If the imported C module fails to compile, massage it until it passes compilation. 4. Once compilation passes, look at the generated COFF object in g23m/__out__/gsm*/obj/l1_{ext,int}. Disassemble it with the tiobjd tool from freecalypso-reveng, and compare against the disassembly of the original ("official") binary blob version we got. Massage the reconstructed source until it compiles into object code that matches the original.
