Topic: Infocast 3.5" not compatible with Falconwing ROM 1_0_3

There are a number of threads on the forum concerning a Chumby One ROM image available for download:

However, beware to anyone thinking of trying to use it on the Infocast 3.5".

One gets the initial bootloader screen, etc., but then it immediately turns itself off.

Looking at the logic-level console output (115200,n,8,1) reveals that it is freaking out because it thinks the (non-existent) battery is overheating:

Please press Enter to activate this console. [   21.200000] power/linux.c - state_machine_work():901 - !!! WARNING !!! Detected the battery running at 317 degrees.  Shutting down to prevent fire

process '-/bin/sh' (pid 716) exited. Scheduling it for restart.

Will there be an updated ROM image that supports the Infocast 3.5"?

Thanks.

Well, yeah, that firmware is *very* old - it predates the very existence of the Insignia device, so it's no big surprise that it didn't work.  Both Chumby One and Insignia 3.5 are based on the basic Falconwing platform, however, they're actually different circuit boards with some different hardware components.

You probably should try firmware 1.0.7 - see this page.  In general, though, it's really not the best idea to run firmware from one product on another product.

Everything I saw in the factory Infocast image (/etc/init.d files, etc.) suggested that there is one Falconwing image that adjusts itself to the branding settings.

I did see the file you linked to, but that presupposes that there is an existing filesystem that is being updated with newer files.

In contrast, the ROM image was suggested in the forums as a means of being able to swap to a different SD card.

If, say, I dd the original SD card to a new, larger one, all the existing partition sizes are maintained.

Trying to resize them using various Linux utilities (fdisk, parted, gparted, etc.) seems to be futile, as all of these utilities balk at the overlapping first partition that the Freescale bootloader expects.

Re: Infocast 3.5" not compatible with Falconwing ROM 1_0_3

As I posted earlier, the ROM image suggested in other posts won't work with the Infocast 3.5".

By trial and error, here seems to be a solution for someone wanting to upgrade a SD card on an Infocast 3.5".  Your mileage may vary.

Take an original SD card, and dd its entire contents over to the new, larger SD card.

When powering up the Chumby for the first time with the new SD card, follow these instructions to restore factory settings:

This will erase any settings that previously existed, but it will recreate the partitions associated with /psp and /mnt/storage, expanding /mnt/storage to the full size allowed by the larger SD card.

Can you please restore the pages or post other / new URLs ?

Could you please also post URLs for the 8" Infocast please ?

Re: Infocast 3.5" not compatible with Falconwing ROM 1_0_3

I'm also interested in a way to build a custom ROM for the 3.5" infocast as opposed to being stuck working with the original.  Does the source for this have to be available per GPL?

Re: Infocast 3.5" not compatible with Falconwing ROM 1_0_3

Falconwing 1.0.7?? And the source is where, exactly?  The latest source mentioned on the source d/l page is 1.0.4, build 2913, and the URL's for that even point to the wrong files.  Would 1.0.7 perhaps be the source for the code on the Chumby Hacker Board V1 that I have been fighting with?
