I have installed OpenMV IDE: 4.0.12 on a macOS Ventura (13.2) and flashed the Arduino Giga R1 with OpenMV firmware v4.5.0. I am able to run example scripts from the IDE. However, I do not see any flash drive mounted. When I plug in the Giga R1 USB cable I see the message: “The disk you attached was not readable by this computer”. To test, I tried the Micropython firmware provided by Arduino and flashed it using the command: dfu-util -w -a 0 -d 2341:0366 -D GIGAR1\_MP\_FW.dfu I can see a mounted mass storage drive “GIGA”. So I guess it has some issue with the OpenMV firmware. ---

Hi, please install the firmware again and check the Erase internal file system checkbox: ![image](https://canada1.discourse-cdn.com/flex029/uploads/openmv1/original/2X/7/7c8febea8807135bdb8ae2fefaf646381d415804.png) ---

I have flashed the firmware again with the Erase internal file system checkbox enabled but it did not solve the issue. ---

> [@yokonav](#): > > The size is very small. 🙄 Yes this confirms it, for some reason only the internal flash storage works on your board/OS not the QSPI, both MicroPython 1.21.0 and our firmware use the QSPI storage. I have a Giga H7 with me and it mounts the QSPI storage just fine, so it’s either your board or the OS that’s the issue, I don’t have a Mac to test with but I will ask someone to test it and get back to you. ---

BTW it seems to be mounting fine on Ventura, so I guess we can rule out an OS issue. Do you have an early prototype/sample or something ? ![image](https://canada1.discourse-cdn.com/flex029/uploads/openmv1/original/2X/d/d38dd8bb9f59e347ce0dede1593d4a31bfa290f9.jpeg) ---

I received it directly from Arduino in March. How can I check whether the QSPI flash is faulty or not? ---

I think March would make it an early dev sample, not sure, about the QSPI, it might not be faulty, although everything points to an issue with it, here’s mine do you have a different one maybe ? ![image](https://canada1.discourse-cdn.com/flex029/uploads/openmv1/original/2X/9/97993e5705e0f1baa49e26fa7b10499d10b6ade9.jpeg) ---

It’s the same. Maybe I need to check the QSPI flash using the Arduino IDE. ---

Yes one of them should be 1MBs the other ~15MBs, so it seems your QSPI is fine, I’m not sure why it’s not working with MicroPython then. Can you please send a picture of the board ? Also, can you try the attached MicroPython firmware see if it works. [firmware.dfu](https://forums.openmv.io/uploads/short-url/r4oNeSrI0BC9BIWshMs9hTo5W5o.dfu) (1.0 MB) ---

Can you please zoom in on the flash part ? Also I’m attaching another firmware that uses a slower clock for the QSPI (40MHz) it might not be the issue but worth a shot. [firmware.dfu](https://forums.openmv.io/uploads/short-url/dqyRkApkhecnYXs1klGvMLyP5IR.dfu) (1.0 MB) Note you should upload OpenMV firmware first and erase the flash, this will ensure the partitions are gone and the QSPI is formatted correctly. ---
