The demo keeps identifying my sdcard as read-only even when it's not. I haven't changed anything. Is there something wrong with my version of MQX 4.2? Or are there additional configurations I need to make?
Here are my specs:
- MK64FN1M0VMD12 chip
- KDS 3.2 IDE
- MQX 4.2
- OPENSDA USB
Wait a minute, does TWR-SER have sdcard slots? Mine doesn't... Maybe you meant TWR-MEM, which is what the example says you need. But, I don't have that module so I'm using the sdcard slot on the TWR-K64 board itself. Can this still work? If so what changes do I need to make?
Hi Dao Yan Lim:
Please see the schematics of TWR-K64, R521 is DNP (Do Not Place), You can check this on your tower board.
Please solder this resistor and try again.
Or you can comment out below line of code in demo.c and try it again.
// lwgpio_set_attribute(&sd_protect, LWGPIO_ATTR_PULL_UP, LWGPIO_AVAL_ENABLE);
