- JC 10:04 AM Software Development: RE: USB Bug within U-boot
- Benedikt,
I am not aware of any known usb bugs with the l138 u-boot. It is also not a feature that we use often. Have you been able to reproduce this on our devkit to try and rule out a potential hardware problem?
Its also possib...

- Hej hej,
I encountered a bug which is related to different usb sticks within u-boot. The USB-OTG port at our custom board is only used as a USB Host.
Some USB-Sticks are only discovered by u-boot using "usb start" if I run usb star...

- Alright glad its working.

- Thanks. That clears that up. Now to load code sourcery and see if I can compiler makefiles. Trying to use CCS 6.0 but all the code seems set up for cygwin gcc or CCS 3.3 (not available). I may ask more questions later.. ;-)

As I understand it, the UBL requires a special header to load the u-boot.bin file. The serial loader program auto add... - IS 11:10 AM Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Ok. The u-boot.bin from the images of the MDK is installed and has bootelf in the help.
So the u-boot-ubl is only for the ftp download? Is that the convention? Is that my error? - JC 11:07 AM Software Development: RE: Serial flash of u-boot-ubl.bin not working

Okay thanks. The MDK u-boot should work with Starterware. - JC 11:04 AM Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Just checked and it appears that our current MDK u-boot has the bootelf command. [[Board_Support_Package]]
MDK_2014-01-03/images/u-boot.bin should be what you need.
The following guide has instructions for updating using tftp but i... - IS 11:00 AM Software Development: RE: Serial flash of u-boot-ubl.bin not working

- Where did you get the u-boot-ubl.bin with bootelf?
- IS 10:51 AM Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Note: I downloaded the images assuming they were ok for serial. I am not up to compiling with cygwin yet. I have bash but not the tool chains (I think).
- IS 10:48 AM Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Oh, and I have used kermit to download. Not sure of all the parameters to load uboot properly. I have a background with embedded systems but no ARM/Linux. Struggling a bit.
- IS 10:46 AM Software Development: RE: Serial flash of u-boot-ubl.bin not working
- I have the u-boot.bin (older version without bootelf) and the u-boot-ubl.bin file (new version with bootelf). The documentation shows the load of uboot from uboot using ethernet. Using the serial loader, it seems to load ok, but then doe...
- JC 10:04 AM Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Found it. u-boot file description from [[Das_U-Boot_Port]]
- JC 10:02 AM Software Development: RE: Serial flash of u-boot-ubl.bin not working
- Also note that if you are in u-boot, you can use the loadb command to send a file over uart. We've used Teraterm to send files over kermit, but there are likely other programs that can do it as well.
- JC 09:57 AM Software Development: RE: Serial flash of u-boot-ubl.bin not working
- I don't remember when the u-boot-ubl.bin file is supposed to be used but according to the [[Reprogramming_a_Dead_Board]] guide, the u-boot.bin file that is output when building u-boot should be used with the sfh_OMAP-L138.exe tool.
- Hi,
I have a custom board without Ethernet (so far). The factory u-boot.bin works fine but I need the bootelf command upgrade. I cannot use uboot to update uboot because it uses ftp on ethernet so I am using sfh-OMAP-L138.exe to load...
