# Build a VT1200 payload/app with the 1987 TI TMS34010 SDK (GSPA/GSPLNK under
|
|
# DOSBox), keeping the linked COFF so dwt/loader/coff.py can inspect it.
|
|
#
|
|
# dwt/loader/build.sh SOURCE.asm [TEXT_ORIGIN [DATA_ORIGIN [BSS_ORIGIN]]]
|
|
#
|
|
# Origins are BIT addresses (the TMS34010 and GSPLNK's SECTIONS origins are
|
|
# bit addresses). With only TEXT_ORIGIN the linker command binds .text alone,
|
|
# exactly like dwt/gui/build.sh. With DATA_ORIGIN/BSS_ORIGIN it binds all
|
|
# three sections, which is what the marker app needs.
|
|
#
|
|
# Outputs, all under dwt/loader/build/:
|
|
# <name>.bin the linked .text bytes (convenience; not a COFF)
|
|
# <name>.coff the GSPLNK output, byte-for-byte (the loader's real input)
|
|
# <name>.map the link map
|
|
# <name>.lst the assembler listing (addresses in bits)
|
|
#
|
|
# ENTRY_SYM=<symbol> adds `-e <symbol>`; default is `_start` if the symbol
|
|
# exists, otherwise no -e (GSPLNK then writes entry = 0).
