Update:
My purpose is to write data to a file in a thread. With append. Writing once
works.
int nbytesi;
nbytesi = write(fd_mmcsd, g_testmsg, strlen(g_testmsg));
if (nbytesi < 0)
{
printf("write_test_file: ERROR failed to write to %s, errno=%d\n",
"/dev/mmcsd0", errno);
}
else
{
printf("write_test_file: wrote %d bytes to %s\n", nbytesi,
"/dev/mmcsd0");
}
close(fd_mmcsd);
sleep(2); <-- when putting in a sleep it all breaks!!!!
nbytesi;
nbytesi = write(fd_mmcsd, g_testmsg, strlen(g_testmsg));
if (nbytesi < 0)
{
printf("write_test_file: ERROR failed to write to %s, errno=%d\n",
"/dev/mmcsd0", errno);
}
else
{
printf("write_test_file: wrote %d bytes to %s\n", nbytesi,
"/dev/mmcsd0");
}
close(fd_mmcsd);

Onderwerp: SDIO MMCSD card is not writing/reading files anymore it does
mount CMD24 -5 error
Hi All,
I had the SD card written with using Nuttx, but then it stopt writing and
reading to and from the SD card. I get a CMD24 error:
mmcsd_eventwait: ERROR: Awakened with 14
mmcsd_writesingle: ERROR: CMD24 transfer failed: -5
It seems to think it wrote bytes, but no file there. What am I doing wrong?
Where could I find more info?
