MIMXRT1170-EVK board (not EVKB) can't enter nShell on 12.4
The codebase I used is Nuttx 12.4. HW is MIMXRT1170-EVK board (not EVKB). The configure command is "./tools/configure.sh -l imxrt1170-evk:nsh".
But I can't find any content on my serial terminal.
Could you check the dip switches on your EVK for the boot method?
Furthermore could you enable CONFIG_DEBUG_FEATURES this should yield more output.
@PetervdPerk-NXP Thanks for your quickly reply.
I already do some test.
- If Do not select "System Type -> Use D-Cache ", then it can enter NSH.
- If select "Use D-Cache" and "Memory Manager Warning Output", then it can enter NSH.
Reproduce this issue:
- select "Use D-Cache"
- Do not select "Memory Manager Warning Output" then it can not enter NSH.
Thanks for figuring out a working sequence. Could you share the log output of a booting IMXRT1170-EVK?

I add some log in nx_start.c

g_npidhash = 4; while (g_npidhash <= CONFIG_SMP_NCPUS) { g_npidhash <<= 1; }
g_pidhash = kmm_zalloc(sizeof(*g_pidhash) * g_npidhash); DEBUGASSERT(g_pidhash);

for (i = 0; i < CONFIG_SMP_NCPUS; i++) { int hashndx;
/* Assign the process ID(s) of ZERO to the idle task(s) */
hashndx = PIDHASH(i);
g_pidhash[hashndx] = &g_idletcb[i].cmn;
/* Allocate the IDLE group */
sinfo("g_npidhash == 4 ----1 \n");
DEBUGVERIFY(group_allocate(&g_idletcb[i], g_idletcb[i].cmn.flags));
sinfo("g_npidhash == 4 ----2 \n");
g_idletcb[i].cmn.group->tg_info->argv = &g_idleargv[i][0];
sinfo("g_npidhash == 4 ----3 \n");

if (i > 0)

}

@PetervdPerk-NXP More info: If I modify "Optimization Level" to "Suppress Optimization" or "custom Optimization", it always works fine.
I am unsure whether this issue is a problem with MIMXRT1170 or a problem with the entire 12.4 system.
Could you check if your problems occur on this commit ? https://github.com/apache/nuttx/commit/9906163bebdfa121b6266917f7413b961206510d
Is V12.4 the first version to include the 1170EVK?
I don't have any other NXP development boards.
The https://github.com/apache/nuttx/commit/9906163bebdfa121b6266917f7413b961206510d commit is the first commit supporting 1170EVK.
I checked out the code based on 2023-12-8, and it has the same behaviors as Ver 12.4.
Which toolchain are you using? I'm running the following
arm-none-eabi-gcc (GNU Arm Embedded Toolchain 9-2020-q2-update) 9.3.1 20200408 (release)
arm-none-eabi-gcc (15:9-2019-q4-0ubuntu1) 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599]
I update my toolchain to the latest version, but the problem still exist.
arm-none-eabi-gcc (GNU Arm Embedded Toolchain 10.3-2021.10) 10.3.1 20210824 (release)
@PetervdPerk-NXP
Can you reproduce this issue in your environment with the original V12.4 code?
In my environment, if I use the original V12.4 release code and use the "imxrt1170-evk:nsh" configuration, this issue can be reproduced 100%.
