is my sam9g43 dead?

[Andrea Bombelli]

i've recently (this morning) received a sam9g45 but when i turn it on, the lan leds(with the cable plugged) blink for 3 secs then turn off,and with or without the microSD(with angstorm) i have no DBGU output.

You think that is an hardware problem?

Help!

On my working board I get the lan blinking thing if the kernel isn't booting correctly.. I think it shows the SoC is alive at least though. You could try the tool that can boot upload to memory etc over USB.. I think it's mentioned on the wiki somewhere.

[Andrea Bombelli]

are you talking about sam-ba..i think... 

yes i've tried also with this, but,every time i try to enable the serialflash or dataflash i get the error:"Script error: Error Initializing DataFlash Applet (Can't detect known device)" or the app freeze

  it seems that the board is'nt recognized properly...or more probably i'm not able to use it :(

There is no DataFlash/NANDFlash on picoSAM9. Depending on kernel
version on your host system (might or might not have sam-ba kernel
module to communicate with devboard) you should see the board on lsusb
command when plugged into host computer usb without
any microSD installed.

yes, i can see it as at91sam samba bootloader!

 so, now the question is:

how can i load android on my board with SAM-BA and make it boot?

You can't. You will have to write the android image to a microSD and
boot from that.

Please mount the microSD on your PC and tell us what you can see.
There should be 2 partitions BOOT and ROOTFS. Try to open BOOT
partition (which is FAT) and tell us the files that you see there.

in FAT32 partition i can see BOOT.bin 51kb and linux.bin 2.479kb it seems to be correct...

Make sure the LCD is properly connected to the connector. If it's not
properly seated then the board it won't boot.

Andreea check the lcd connector.
First is necessary to pull little the black side from connector then put
the connections from lcd and the push the black side to the place.
I think this aspect is necessary to be write in wiki page.

LCD cable checked and fully inserted...

...the CR1225 battery is  needful to boot?

nope. The time won't be saved without it.. but it drifts a lot anyhow. 

[Andrea Bombelli]

 i'm in a dead point...i don't know what to do 

i also tried to change sd card but results don't change

Are you writing the microSD from windows or linux ? If on windows I'd
try WinImage, seen some microSD fail to boot
when written with dd from windows although the contents were fine upon
inspection.

Otherwise I mostly suspect some bad connection (LCD, microSD). I
haven't seen one picoSAM9 unit failing to boot.

If you still don't manage to boot just write a mail to support
requesting a RMA and tell them it's not booting and you have debugged
with us on picosam9 google group.

[Andrea Bombelli]

i have written it from linux and windows and i checked again the LCD connector.

 I will send an email to support today

Thank you thousand for the support!!
it's a very nice group!!

[David Retana]

Hi Andrea,

Today I have a similar issue. :(

Did you send the email to support ?

How did you solve this issue?

Thanks for share your experience

[Erik van Luijk]

We also observed boot issues on one of out miniboxes. The fix was to re-solder the common side of RR23 (near the ethernet chip).

regards,

Erik
