Burns, I think the initMRAM() is there. I merged your branch in. I see the function call in ConsolTask() right after the SPInit() calls for the MRAMs. But I also see a lot of MRAM errors at boot. Error 19s and Error 20s...
Corey, I tried //test_file and that did not work either.

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.

I tried a simple example but I can't open a file. Is there a volume

that I need to specify? I presume you don't need to create a directory.
"/" 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?

I assumed that since this was ARM it was little endian.
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).
