Headless Bitstream

[miro]

Hi Everyone,
I am trying to use my Parallella in headless mode. I created the SD Card as described, and this is booting fine, starting Linaro with XCFE on HDMI. Then I downloaded the parallella_e16_headless_gpiose_7020.bit.bin from github and replaced it on the SD-Card naming as described. But the Parallella won't boot up then.. HDMI is as expected off, but I don't get the network working. (unfortunately I don't have serial cable, so I can't see what went wrong. ) Renaming the original parallella.bit.bin with HDMI back boots up immediately...(with working network)

Does anyone got this working? If so, can someone post me the md5 of the bin file, if its downloaded correctly?

Thx
Miro

Hi Miro,

I get:

dad03fff40a9b31e807e0f9291657517 parallella_e16_headless_gpiose_7020.bit.bin

Note that the Linux device tree will also need updating if the Parallella is being configured without a HDMI controller. I'd also strongly recommend getting a serial cable so that you can see what is going on, but as has been pointed out elsewhere, you should be able to put the SD card in another machine to read the logs.

Cheers,

Andrew

Thanks, my checksum differs, so I'll have to download it again.. And thanks for the hint, for sure this one can make troubles too.. I'll look for one suitable serial cable for me..
meanwhile I'll keep it in HDMI and try to get roff the matmul-16 error

Hi Andrew,
sure, that was a good question I was dowloading the bitstream "as raw view". At least the content has similar structure to the original file (biary diff). I guess it was the device tree. I downoaded it from the tgz archive togheter withthe device tree and now it is working fine in headless mode (howver the md5 differ to yours, so its still different one)
