PLATFORM=PM3ICOPYX has not compiled at all -- it dies on obj/start.o,
before anything else is built:
common_arm/gpio/gpio_hw_at91.h:77: error: 'GPIO_FPGA_ON' undeclared
(first use in this function); did you mean 'GPIO_FPGA_DONE'?
PA26 has two different jobs depending on the FPGA, per
config_gpio_proxmark3.h:
#if defined XC3
#define GPIO_FPGA_SWITCH AT91C_PIO_PA26
#else
#define GPIO_FPGA_ON AT91C_PIO_PA26
#endif
ICopyX has no FPGA power rail to switch; that pin selects the FPGA
instead. But Gpio_FPGA_ON_High(), Gpio_FPGA_ON_Low() and
gpio_fpga_on_setup() all referenced GPIO_FPGA_ON unconditionally, so the
symbol simply does not exist on XC3.
'This board has no FPGA power switch' is already a supported case: the
AT32 port stubs both accessors with a bare '// Unsupported' comment, and
PM5 depends on that, while Gpio_FPGA_SWITCH_High()/Low() two functions
further down in this same header are guarded with #ifdef for the mirror
case. The AT91 header just never grew the XC3 arm. All three now carry
the same guard.
fpga_loader.c calls Gpio_FPGA_ON_High() from shared code; on ICopyX that
compiles to nothing, which is correct -- the rail is always on.
Verified: fullimage builds for PM3ICOPYX (356832 bytes, with
PLATFORM_EXTRAS=FLASH), and for PM3RDV4, PM3GENERIC, PM3ULTIMATE and
PM5. For the boards that do have the pin the guard costs nothing -- the
.text section is byte-identical before and after, 289464 bytes on
PM3RDV4 and 243584 on PM3GENERIC; only the embedded build timestamp and
source hash move in the full ELF.
