Hi,

Please open a new case for this question as it is not directly related to the original topic. (Also, I will be OoO from three weeks from today and unable to reply.)

dear Einar Thorsrud

By the way

I encountered a strange problem with mcuboot in ncs1.6.0, and the program has been running for a long time to FIH_PANIC and It's not going to work.

FIH_CALL(boot_go, fih_rc, &rsp);
if (fih_not_eq(fih_rc, FIH_SUCCESS)) {
BOOT_LOG_ERR("Unable to find bootable image");
FIH_PANIC;
}

Please ask what causes this？

best regards

Hi,

It is good you have a work around, but it seems odd. I agree this seems like a compiler issue. I am not able to find any reference to this, but perhaps it is worth testing a different GCC version (though the workaround seems fair enough).

I put the config_ COMPILER_ Opt = - LM "into my pri.conf, the problem still exists, But there's one amazing thing，When I put the following code in *. C,Even though I don't make any calls。The compilation is successful。

It looks like there's something wrong with the compiler。

#include <math.h>

#if(1)
int compare(const void *, const void *);
void test(void)
{
const char *a[10] = {"enter", "number", "size", "begin", "of", "cat", "case","program","certain","a"};
float op;
float result;
op = 0.08;
result= sqrtf(op);
result= log10f(op);
result= expf(op);
result= cosf(op);
qsort(a, 10, sizeof(a[0]), compare);
result= tanf(op);
result= sinf(op);
result= logf(op);
}

int compare(const void *c, const void *d)
{
int m,n,r;
char **a, **b; // !!
a = (char **)c;
b = (char **)d;
m = strlen(*a);
n = strlen(*b);
r = m - n;
if (r != 0)
return r;
return memcmp(*a,*b,m);
}
#endif

best regards

Hi,

Have you attempted to build with CONFIG_COMPILER_OPT="-lm"?

(In SES you add compiler options by clicking Extended Settings in the dialog you get from Open nRF Connect SDK Project..., and then add it under Extra CMake Build Options)

My current library just uses floating point operations，The device IC is nrf52840, my pri.conf is
CONFIG_FPU=y
CONFIG_NEWLIB_LIBC=y
CONFIG_CBPRINTF_FP_SUPPORT=y
CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y

but There are many such errors when compiling the library

Are there any good suggestions for me to solve these problems ？

I found these functions in math. H, but I can't use them

It seems to have something to do with this condition

#if __ISO_C_VISIBLE >= 1999

best regards

Yes, that should be no problem (but note that it must map the IC you use. For instance if the library is built to use floating point instructions you cannot use it with nRF5 devices that does not have and FPU, etc).

Thank you very much for your reply. If I use GCC library, is that ok?

Hi,

No, that will not work, primarily because of different wchar size between Keil and GCC (which is used by SES).
