openmano-mpy/ports/powerpc/Makefile, branch master MicroPython source and hardware configuration for OpenMano powerpc/uart: Choose which UART to use at build time, not runtime. 2020-05-29T12:54:55+00:00 Joel Stanley 2020-05-26T03:29:55+00:00 f03d030080ccf89c6ad677c818c949c3bd71ec37 Microwatt may have firmware that places data in r3, which was used to detect microwatt vs powernv. This breaks the existing probing of the UART type in this powerpc port. Instead build only the appropriate UART into the firmware, selected by passing the option UART=potato or UART=lpc_serial to the Makefile. A future enhancement would be to parse the device tree and configure MicroPython based on the settings. 
Microwatt may have firmware that places data in r3, which was used to
detect microwatt vs powernv.  This breaks the existing probing of the UART
type in this powerpc port.

Instead build only the appropriate UART into the firmware, selected by
passing the option UART=potato or UART=lpc_serial to the Makefile.

A future enhancement would be to parse the device tree and configure
MicroPython based on the settings.
powerpc: Set better default compiler. 2020-05-27T07:02:04+00:00 Joel Stanley 2020-05-26T03:37:09+00:00 b65482ffa8715f3eeeb593e26d96d80bd77e0dfd Most developers use a compiler which is called powerpc64le-linux-gnu-gcc.

The linker script was included in the "$^" inputs, causing the build to
fail:

 LINK build/firmware.elf
 powerpc64le-linux-gnu-ld: error: linker script file 'powerpc.lds' appears multiple times

As a fix the linker script is left as a dependency of the elf, but only the
object files are linked.
all: Enable extra conversion warnings where applicable. 2020-04-18T12:42:28+00:00 stijn 2020-04-09T11:59:11+00:00 30840ebc9925bb8ef025dbc2d5982b1bfeb75f1b Add -Wdouble-promotion and -Wfloat-conversion for most ports to ban out implicit floating point conversions, and add extra Travis builds using MICROPY_FLOAT_IMPL_FLOAT to uncover warnings which weren't found previously. For the unix port -Wsign-comparison is added as well but only there since only clang supports this but gcc doesn't.
