Unfortunately the simple coulomb counting chips have the disadvantage

we now use it in a commercial product.
I recommend having a look at the datasheet for the DS2782 to see what
methods they use for determining the remaining charge in a battery and
to get an idea of the complexity of the problem.
Good luck!

supports JFFS2). JTAG is good for production
installation but USB DFU is ideal for field upgrades or bricked-system
recovery.

i'm gonna take a stab anyways. does this apply to Linux only and not
open source boot loaders (like U-Boot) ?
It applies to anything in the embedded Linux

Hi,
a while ago I was working on a SoC with 200MHz ARM926EJ-S CPU
and integrated 100Mbit ethernet core, connected on internal
(fast) memory bus, with DMA. With iperf I measured:

... no thanks.
I know that there are sites which list compatible USB and PCI WiFi
devices, but I've not seen anything that goes down to the OEM module
level. Is there a webpage somewhere of OEM Linux compatible SDIO Wifi
modules?

Hi,
can someone point me in the right direction to choose an OEM WiFI +
Bluetooth chipset/module suitable for an embedded Linux system? I'd
prefer if it was connected via SDIO.
Sorry to answer my own question.
a monolithic kernel, or is it split into minimal with
modules loaded from, say, JFFS2 on NAND?
* are you using JFFS2 or UBIFS?
Any info is much appreciated, thank you!
