What should I add to board configs and compiler defines to make build of Espruino 2v22 for STM32F4 with
RESIZABLE_JSVARS
enabled?I added
-DRESIZABLE_JSVARS
into compiler options, but got this error:/usr/lib/gcc/arm-none-eabi/12.2.1/../../../arm-none-eabi/bin/ld: /usr/lib/gcc/arm-none-eabi/12.2.1/../../../arm-none-eabi/lib/thumb/v7e-m+fp/softfp/libg_nano.a(lib_a-sbrkr.o): in function `_sbrk_r': /home/pere/src/newlib-salsa/build_nano/arm-none-eabi/thumb/v7e-m+fp/softfp/newlib/libc/reent/../../../../../../../../newlib/libc/reent/sbrkr.c:51: undefined reference to `_sbrk' collect2: error: ld returned 1 exit status make[1]: *** [make/targets/ARM.make:3: bin/horizon_2v22_dponyatov_250110.elf] Error 1 make[1]: Leaving directory '/home/dponyatov/Espruino' make: *** [mk/all.mk:5: all] Error 2
What I need is enabling block allocation mode but build fw with three precompiled blocks:
- RAM 128K
- CCMRAM 48K (3/4 of CCMRAM)
- optional extRAM (up to 16 Mb)
PS: I take old 2v22 thus modern versions compiles into ELF file with broken LMA/VMA table but I don't have time to fix it (all source code debug info bounded to zero address etc)
- RAM 128K

Good day
I built
espruino_2v24_stm32f4discovery.elf
which this command line:~/Espruino > BOARD=STM32F4DISCOVERY DEBUG=1 make
my .gdbinit:
## on load b Reset_Handler b SystemInit b main monitor reset halt
When I try to load .elf file into the
gdb
I got some strange address binding for source code lines:
0x3930 (without startup_stm32f4xx.s link)
0x58324
0x35076It looks like address bindings to Flash ROM are totally incorrect.
At the same time, when I build my own empty startup code (generated by latest CubeMX), there are no any problems with addresses or source code.
Next, another problem is I always got system stopped at
0x800076c
address that looks like start ofEXTI0_IRQHandler

@Gordon: Did you maybe tested some experimental version of
JsVars
allocation for multiple non-continues memory banks for some board with all tiny-bits optimizations enabled?As I see in source & debugger, for STM32F4 series there is defult build used with a single preallocated array isn't it?
