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
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
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...

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...
