crt_emu_cm_redlink segfault when flashing to mimxrt1050-evk

[dabortol]

Hi everyone,

I get consistent segmentation faults on crt_emu_cm_redlink when trying to flash binaries to my mimxrt1050-evk board.

The issue seems to be related to the size of the binaries (or of the sections?) : the smaller they are the most likely I run into the segfault.

Segmentation fault (core dumped)

When running the flashing command through gdb, I get:

 Program received signal SIGSEGV, Segmentation fault.
__memmove_avx_unaligned_erms () at ../sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S:269

Here are the sections' size from a binary that leads to segfault:

text   data bss    dec    hex 
109964 200  562376 672540 a431c

Any help would be appreciated

Hi，
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I think I need more information about the issue, so I was wondering if you can demonstrate the steps of replicating the issue, it can help me to figure it out.
Have a great day,
TIC
