CF 06:27 PM MitySOM-5CSX Altera Cyclone V Software Development: Build Preloader failed in Windows 10

Hello,
We used to be able to build preloader in Windows 7 environment. However, not any more after we upgraded to Windows 10. Same u-boot package and same build procedures. So we think the OS change might be the course for the failur... chad fan

JC 06:47 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: GPIO toggling/chattering while performing NAND read.

Worked on this with Zafer. Posting this to tie up the public post.
The solution to this is to pinmux the gpio0_27 pin in the MLO as a gpio.
Note that all the AD pins will be driven as outputs during the ROM bootloader. This can n... Jonathan Cormier

Have you had any chance to create the problem on your side, I mean since the discussion started?

I will do that.
Thank you very much Dan.

Hi Dario,
You could also try using the "sync" linux command after you copy the rbf over. That should flush anything out to the SD card. I normally do a sync and a reboot after updating the RBF. Seeing as the filesystem is read/write d... Daniel Vincelette

DR 02:15 PM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: FPGA programming problems

Hi Dan,
Don't worry, I really appreciate your help.
Yes, running “reboot” works and it is the only way to change the FPGA configuration without rebooting the system multiple times. Indeed, even if I change the rbf and then I turn the ... Dario Russo

Hi Dario,
My apologizes for the later reply, it was a long holiday weekend in the states.
So by running "reboot" after copying over the RBF fixed your problem?

Yes, exactly. We did that test before.
It doesn’t show up in 2013, but shows in 2018.

Hi Zafer, just to confirm that the 2013.10 u-boot doesn't chatter but the 2018 one does? Jonathan Cormier

Hello,
The last post was about 2 months ago. I am having exactly the same problem.
Our environment uses previous mityARM board (with single DDR2 version).
Before continuing further, I wondered if there has been any progress.
I teste... Zafer Elbi

Hi Dan,
thank you very much for helping me with this problem.
Attacched you can find the boot logs for the three cases required.
The checksum verification it is ok by comparing the linux checksum with the PC file. Instead there is no ... Dario Russo
