Chris, I assume that you did add the "initMRAM" near boot (right after
the SPI init). If not, you may have to do format the file system after
doing it because it may have the size and the partition setup wrong
otherwise.

"/" should be the volume name, but maybe you need two of them? I wasn't
sure from what the documentation said.
If you can open "//test_file", then that's what it is.

Here is the code, but the open fails with "No such file or directory"
// TEST File System
char *test_string = "This is data";
int32_t fp;
printf("FS Test: Writing:\n");
fp = red_open("/test_file", RED_O_CREAT | RED_O_WRONLY);
if (fp != -1) {
printf("Writing string\n");
int32_t numOfBytesWritten = red_write(fp, test_string,
strlen(test_string));
if (numOfBytesWritten == strlen(test_string)) {
printf("Success\n");
} else {
printf("Write returned: %d\n",numOfBytesWritten);
if (numOfBytesWritten == -1)
printf("Unable to write to file: %s\n",
red_strerror(red_errno));
}
int32_t rc = red_close(fp);
if (rc != 0) {
printf("Unable to close file: %s\n",
red_strerror(red_errno));
}
} else {
printf("Unable to open file: %s\n", red_strerror(red_errno));
}
Any thoughts?

Yeah, I would have too. But apparently ARM can go either way.
Turns out
that for some reason the automotive world seems to standardize on
big
endian. This has caused nothing but hassle on the TMS570 (the
STM32L is
little).
