Re: Update UBOOT from OS

Sorry of the late update.

I redid the soldering and tried to flash the B3 manually, but still no luck. It is simply impossible to change the contect of the flash, while reading from it works perfectly. Is there an explanation for this situation?

Re: Update UBOOT from OS

I tried manual flashing. Apart from a different file size of the u-boot.kwb, our sessions look alike, only that for me the flash was unsuccessfull. I do not know, why we have different sizes, but for flashing, this souldn't be an issue, shoud it? I compiled the u-boot code on the B3. I can check fro...

Re: Update UBOOT from OS

I booted with usb key in place, pressing the rear button. The output was the same as already quoted in my last post. On the u-boot command line, I typed "reset". The board was reset and the system booted into my os. There, I read out the u-boot on flash using mtd_debug read /dev/mtd0 0 786...

Re: Update UBOOT from OS

Hi, thank you for hanging on this thread so patiently! I missed, that the zip of the 3TB update unpacks into a folder "install". When I put the u-boot.kwb into this folder it is found and read correctly (correct size read), but I am only dropped onto the u-boot command line. --------------...

Re: Update UBOOT from OS

Thank you MouettE for your advice. I tried it with and without seriel connection, with and without lan cable, using the upper and the lower usb port. The thumb drive I use has a fresh msdos partition table with a single vfat partiton on it. However, the u-boot on the nor flash stays at 2010.06. The ...

Re: Update UBOOT from OS

I now also tried nandwrite and flashcp. Both didn't report an write error, but the content of the flash did not change. At least flashcp reported that veryfing the write failed, since source and target differ. Do I need to unlock the flash before writing? I found an unlock option for flash_erase and...

I have a serial connection to by B3. Usually I use screen to connect. How do I inject the magic chars (0xBB 0x11 0x22 0x33 0x44 0x55 0x66 0x77) to invoke the hardware loader?

So what I get from [1] is that the fix which "should" end up in the u-boot image but can be moved to the kernel in a way that L2 is disabled before used for the first time, correct? If this ends up in mainline, it would imply, that it should be possible to boot an official kernel, from 3.1...

Can you please elaborate a little on what your patches mean. Have you disabled the l2 cache in the kernel, such that it works with older u-boot versions? Will this be linux mainline with kernel 3.15. This is quite in a distance. We are at 3.12 right now...

Thank your for clearing this up for me.

Well, just type

sudo ifconfig eth0 hw ether 02:01:02:03:04:08

as suggested in the work around. If your use a real root account and not sudo omit the sudo. I am working on it and come back here if I found sth. worth writing about.

How to connect to the B3 using sr232 serial connection

I try to connect to by B3 using a serial cable. I have read [1] and soldered the leads correspondingly. Since my local supplier did not carry the sr232-to-usb thing as recommenden in [1], I just got a plain serial jack and soldered the pins 2, 3, and 5 for rx, tx, and ground, respectively. I use scr...
