- Hi Dominik,
Glad you found the solution! I know I've spent many hours working on kernel issues to have them solved with one line changes.
Thank you for the update!

- Hey Dan!
I found the culprit! :)
As it often happens in linux kernel, the solution turns out to be very trivial.
It requires enabling CONFIG_LBDAF, which extends kernel partition device sector count width from 32 to 64 bits.

- Hi Dominik,
The only thing I could really think of was try the very verbose USB output like you initially suggested or add printk's to the USB driver. Try it with a flash drive and then the 8TB devices and compare the outputs.
I'm ... - DM 09:20 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: 8TB USB Mass Storage device being unreadable
- Hey Dan,
Thanks for your reply.
Building CHR_DEV_SG into mitysom kernel doesn't seem to fix anything. The SG initialization message appears now though. I've also tried to use /dev/sg0 device as the dd input with and without DEV_SD dr... - DV 11:51 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: GPIO pins high during Pre-loader/Uboot 5CSE-H4-3YA
- Hi Brian,
Unluckily the initial values of the GPIOs aren't configurable from what I've seen. You could edit board/cl/mitysom-5csx/mitysom-5csx.c and in the board_init function set the GPIOs values but I'm not sure how long it takes to...

- Hello,
I have a project where I hooked up leds to several gpio lines. The gpio lines go high for about 5 seconds (which is not acceptable for this application) during what seems to be the preloader/uboot stage and then go low once the...

- So this might be a red herring but in the pi's dmesg it has the following line, which the MitySOM doesn't:

- Hello Dan,
Yes. I tested with 8 and 16GB USB sticks as well and it works just fine, so the culprit might be in the unusual size. - DV 09:21 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: 8TB USB Mass Storage device being unreadable
- Hello Dominik,
Have you tried a quick test of using a smaller flash drive with the MitySOM? Just to see if we can get a baseline, I've used 8GB/16GB flash drives on the MitySOM without issue.
Thanks!

- Thanks so much. That info provided the missing link for the Device Tree

- The kernel used on MitySOM is 3.16.0.
- Hello!
I'm trying to use an USB device enumerating as a 8TB Mass Storage with 5CSX-H6-42A kit. It's connected through a mini-USB OTG adapter.
It doesn't appear to be working properly. Any read from the device ends up returning 0 byte...

- Hector,
I'm glad you got it working. I'm not sure the exact difference between what you did and the official instructions, but it may be that your "direct copy" approach may not have brought over all of the libraries or extensions th... - HB 03:05 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Java Runtime Environment for MitySOM1810f

I got some help from a friend that use to work with Raspberry pi and we took other way, we just downloaded the "JAVA SE EMBEDDED":http://www.oracle.com/technetwork/java/embedded/embedded-se/downloads/index.html the versio...
