Hi,
I'm now quite stuck without the ability to use use the host mode.
I have noticed on Rocketboards something recent that seems related to the issue I'm facing :

AB 11:29 AM FPGA Development: RE: Load FPGA Timeout Error

Max,
Thank you for posting that.
You are correct that if VBAT is too low the module will either not boot at all and/or will not allow the FPGA to be programmed. We believe that on earlier development kits the ESD bags may have cont... Alexander Block

MB 10:41 AM FPGA Development: RE: Load FPGA Timeout Error

Hi Dan,
I had similar problem last week. After two week I tried to run my development board loading the FPGA with JTAG and using Uboot.
JTAG was not able to connect and with Uboot the return message was:
altera_load: Failed with e... Massimo Buratto

MW 06:34 PM Software Development: RE: U-Boot with large uImage containing initramfs

Hi Nicholas,
A little confused. Your build_ramdisk_image.sh appears to be building a 1 GB image for loading an SD card, which contains including multiple partitions, etc.
You want to create a raw ext2 or ext3 image only, not a ful... Michael Williamson

JL 12:23 PM Software Development: RE: Compiling Memory Size into U-boot

I think I see my error.
The ubootenv.bin file doesn't go into any of the three partitions generated by that automated script.
If you wish to just update the ubootenv.bin file this is the command you need:
dd if=ubootenv.bin of=/d... Julio Liriano

JL 10:09 AM Software Development: RE: Compiling Memory Size into U-boot

From that script to combine the uBoot image with the rootFS as well as the uBoot blob, I gleaned that
to write the uBoot blob only is to do execute this command:
dd if=ubootenv.bin of=/dev/sdb2 bs-512 seek=1
However when I inser... Julio Liriano
