hello, world\n
we’re currently in the design phase for a rocketchip RISC-V project with two
harts.
Think a common HW platform where each hart drives a separate telescope unit.
The C code for each telescope is basically identical with the exception of
memory mapped registers and interrupts.
Our idea is to compile the C code twice and link with different linkerscripts,
separating the images in RAM
via different MEMORY { RAM: ORIGIN = 0x######## } declarations. A bootloader
loads the images
to different addresses and branches depending on mhartid, starting two separate
RTEMS applications, each
of which runs 10 tasks. There’s no communication between the RTEMS instances.
Are we attempting something crazy (too complex) and we should instead look into
<your suggestion here>?
If not, is there a simple way to compile an app twice for different RAM: ORIGIN
values?
I tried using a Linkerscript with -Wl,-T,Linkerscript with a different MEMORY
but this draws a warning such as
warning: redeclaration of memory region `RAM'
and uses the value in the BSPs linkcmds file. It looks like the last
declaration wins and the linkcmds is
always read after linker scripts specified by my -Wl command line option.
