Hi all!
Some time ago I purchased an IBM X23 notebook (nice thing BTW) with
Bluetooth. The Bluetooth chip is, of course, a CSR one, labeled as ITSE.
IBM offers a Bluetooth firmware upgrade for it to help support of
multiple connections.
So I would like to upgrade my firmware using the dfutool. IBM's uprade
file can easily be unpacked and what you get is the, I guess, proper DFU
file for the upgrade.
Using the dfutool I can nicely backup my firmware to a file - works like
charm!
But when I try to flash the new firmware the dfutool waits a couple of
seconds at "switching device to dfu mode", then sais "Dowloading
firmware" without progress indication and then sais "Can't get status:
Broken pipe (32)".
Pity, so close but yet so far ;)
If it is of help I can provide the original and update firmware files.
Here is additonally what hciconfig tells me about my chip:
root@miu:~ # hciconfig hci0 revision
hci0: Type: USB
BD Address: 00:80:98:24:80:BE ACL MTU: 128:8 SCO MTU: 64:8
HCI 11.3
Chip version: BlueCore01b
SCO mapping: HCI
root@miu:~ # hciconfig hci0 version
hci0: Type: USB
BD Address: 00:80:98:24:80:BE ACL MTU: 128:8 SCO MTU: 64:8
HCI Ver: 1.1 (0x1) HCI Rev: 0x73 LMP Ver: 1.1 (0x1) LMP Subver: 0x73
Manufacturer: Cambridge Silicon Radio (10)
And this is the name of the new firmware file
ITSE_00003_07_IBM_BDC_Firmware128_Rev310.dfu
So, does anyone have an idea how to debug or even fix this?
If yes, I would be quite glad ;)
Cheers

no, because dfutool simply ignores them.

you can use "verify" to see if the DFU file is at least valid.

The dfutool is not perfect. I only tested it with a small bunch of
devices and most of them were BlueCore02 or later.

This is a very old firmware and maybe the boot loader on the chip is
even older. Maybe it is broken and need some special tweaks to make it
working. Sometimes increasing the timeouts inside the code might help,
but you can also render your device useless.

Hmm... I just compared the original DFU and the upgrade DFU using the
verify option:

Might the missing product and vendor ID be the problem with upgrade
