Re: ARMv8/AArch64

Update: I had the problem with executing loops. The program stucked in /py/vmc.c in MP_BC_JUMP by the macro DECODE_SLABEL. The ISSUE-3201: https://github.com/micropython/micropython/issues/3201 , helps to find the right keyword: unaligned access AArch64/ARMv8 supports unaligned access out of box but...

Re: ARMv8/AArch64

further changes: set function failed "def test():",

solved with: in mpconfigport.h I changed the typedef's

typedef int64_t mp_int_t
typedef uint64_t mp_uint_t;
typedef long long mp_off_t;

and defined "#define MICROPY_OBJ_REPR (MICROPY_OBJ_REPR_D)"

Re: ARMv8/AArch64

And finally calling "readline_init0" in main.c also solved the issue a post before :D

ARMv8/AArch64

Hi, I tried to port the "minimal" to AArch64 but the repl does not work properly. I get the access to the REPL ">>>" but if I type a simple "print", the controller executes his whole ARMv8 register and get stucked But if I enter the Paste-Mode and paste some lines, it works fine. If the lines increa...

Re: How to port Micropython to TI CC13xx / CC26xx?

Perhaps this can help:
viewtopic.php?f=12&t=1823

Starting point:
* use minimal, edit/change linkerfile and Makefile.
* add HAL drivers from your board
* add in uart_core.c functions from TI's uart, usb or something else...to get repl access.

Re: How to compile the Project in IAR studio for STM32F429

I have the same problem with Greenhills compiler and the qstr gen. Because the preprocessor output not match exactly to this lines: https://github.com/micropython/micropython/blob/master/py/makeqstrdefs.py#L26. I tried a little but no working solution, yet. Maybe someone had the same problem and can...
