SD Card not registering on Pyboard SF6W

[kbrenner]

Hi,

I have a Lexar 32GB SD card attached to the SF6W. I have several SF6W's, and it has worked on others, but for this device, it won't register it. I have confirmed that sys.path does not show '/sd', and upon trying to access '/sd', I recieve OSError: [Error 19] ENODEV. Has anyone else experienced this or have any troubleshooting suggestions?

Best,
Kevin

I have several SF6W's,

This indicates it's probably not something you're doing wrong!

I assume you're doing:

Code: Select all

import os
import pyb
os.mount(pyb.SDCard(), "/sd")

Has anyone else experienced this or have any troubleshooting suggestions?

I guess the main thing I'd try is to see if the block device works at all:

Code: Select all

import pyb
b = pyb.SDCard()
print(b.read(0))

I get a block ending in b'U\xaa' with a partition table in the final 64 bytes.
