JC 03:13 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Getting the Splash Screen to Appear Earlier

There was some change I think around TI's SDK 9, that greatly delayed the /dev/fb0 creation. I didn't dig into it at the time, but I agree its not ideal.
I do think that getting the u-boot splash screen support working would make the... Jonathan Cormier

HW 02:44 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: AM62A: Getting the Splash Screen to Appear Earlier

Good morning,
I am finding that the psplash screen comes up very late while the kernel is initializing to the point where it sometimes does not appear because it is started as the kernel boot is completed.
After running systemd-ana... Holden Wozniak

AF 09:33 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Using GPIO command on UBoot command line...is there any pin mapping between HPS pin # and GPIO pin #?

From Dan at CL (Thanks Dan!)
Our reference project has the following HPS IO set as GPIO:
- GPIO40 — edge pin 264 — SDMMC_D4/USB0_D4/HPS_GPIO40
- GPIO41 — edge pin 266 — SDMMC_D5/USB0_D5/HPS_GPIO41
- GPIO48 — edge pin 38 — TRACE_C... Austin Franklin

AF 09:31 PM MitySOM-5CSX Altera Cyclone V Software Development: Using GPIO command on UBoot command line...is there any pin mapping between HPS pin # and GPIO pin #?

Hi,
I have the CriticalLink UBoot image on a terminal program. There is the GPIO set/clear/toggle command. It wants a pin number. I have a logic analyzer on HPS GPIO 53 (pin 26 on the MitySOM connector). After UBoot comes up, that... Austin Franklin

Hi Austin,
You are correct that the Cyclone V cannot drive this pin. It is a configuration control input which must be driven externally via HW if needed. You would drive this pin low if you needed to reset, reconfigure the device or ... Mike Fiorenza

On the CriticalLink MitySOM-5CSX development board, there is an LED D100 connected to nCONFIG (pin 39). According to the Intel/Altera documentation, nCONFIG is an input to the Cyclone V. I don't find anything in the Intel/Altera docs t... Austin Franklin

Hi Samuel,
Did you follow the instructions here and are still seeing this issue: https://support.criticallink.com/redmine/projects/mitysom_a5/wiki/A5E-DMA-Example#The-application-hangs-or-reports-errors-on-the-second-and-later-runs

SP 06:56 PM MitySOM-A5 Software Development: RE: make_sd.sh doesn't take command line parameters

We have tried the new DMA driver and FPGA.
We have the following situation on each reboot.
The first test pass.
The second and third test fail.
The fourth hangs.
Is it expected behavior ?
Thank you for your time,
Samuel :)... Samuel Paul
