Hi U-Boot Hackers,
I have some problem regarding DHCP on my Atmel NGW100 board, when using dnsmasq on the server side. I want to use the device for some kind of automatic test suite runs.
Does the support for this device is known to work in 2015.01?
I have not tested and do not own a ngw100 but it is likely that it is still working. Avr32 in general has had very little changes in the past. I personally have access to a ngw100mkII, grasshopper and stk1002 board. They are tested from time to time. AFAIR there was no breakage in the last two or three years. I have to admit not all of these boards tested with 2015.01 yet. But I do not expect any surprise here.
Can I update the old existing U-Boot boot loader directly or should I use FlashUpgrade tool from Atmel? (http://mirror.egtvedt.no/avr32linux.org/twiki/bin/view/Main/FlashUpgradeUsag...)
I always do it directly or with my jtag ICE. It seems the FlashUpgrade is just some scripting to advise u-boot to do the update. I would prefer to do it for my own.
Thanks for the advice. So I put my u-boot.bin file on tftp and do following: tftp 0x10400000 u-boot.bin protect off 0x0 0x1ffff erase 0x0 0x1ffff cp.b 0x10000000 0x0 0x1975c
ouch, copy from should be 0x10400000
Ah, you are right. Copy and paste from some info from the net. I used 0x10400000 to load the linux kernel.
protect on 0x0 0x1ffff reset
While 0x1975c is the size I get after loading the u-boot.bin file via tftp?
looks good. You could use some variables here:
tftp 0x10400000 u-boot.bin protect off 0x0 +${filesize} erase 0x0 +${filesize} cp.b ${fileaddr} 0x0 ${fielsize} protect on 0x0 +${filesize} reset
fileaddr/filesize env will be set after successful transfer, please check with your running version if they are set correctly first.
Yes, fileaddr and filesize seemed to be set correctly.

But unfortunately the device is dead after the erase command.
Where do you live with your JTAG programmer? ;) Is a AVR dragon device usable to reprogram the NGW100? Or what is my cheapest choice now?
best regards Waldemar
