openmano-mpy/ports/powerpc, branch master MicroPython source and hardware configuration for OpenMano ports: Remove def of MP_PLAT_PRINT_STRN if it's the same as the default. 2021-02-04T11:39:17+00:00 Damien George 2021-02-04T03:43:24+00:00 7c4435459261f1ea93577938b1ab281239d159e7 To simplify config, there's no need to specify MP_PLAT_PRINT_STRN if it's the same as the default definition in py/mpconfig.h.

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.

For the unix port -Wsign-comparison is added as well but only there since only clang supports this but gcc doesn't.
