Hello all!
This time I have a Pirelli A112 ADSL Modem, which I would like to use to prototype with some stuff (removing ATM, ADSL, ISDN and PPPoE stuff since it's not necessary).
It has a CPU chip marked as BCM6332KFBG, but either the bootloader and the original image treat it as a BCM96338.
Also, there is an 4Mb SPI Flash, and 16Mb of RAM.
Originally, the board ID was "PirelliCMB_1PG", but for testing purposes I've selected "96338W".
Other options:
96338SV ------- 0
96338L-2M-8M ------- 1
96338L-65-2M-8M ------- 2
96338W ------- 3
96338W-20P2 ------- 4
96338E4 ------- 5
PirelliCMB_1PG ------- 6
96332CG ------- 7Well, since the only "compatible" ID is "96338W", I've selected it, and flashed the 64k-CFE. It didn't worked, because a Kernel panic appeared.
Here I attach the full serial log, in which one can see some interesting things:
in the bootloader:
* Sizes and positions informed by bootloader doesn't match others that I've seen in the official BCM63xx thread
* Serial flash device: name , id 0xc216, size 4096KB (No chip name, but its an KH 25L3205D 32MBit = 4Mbyte)
in the kernel:
* board_bcm963xx: CFE version: unknown
* physmap-flash physmap-flash.0: map_probe failed
* VFS: Cannot open root device "mtdblock2" or unknown-block(0,0): error -6
CFE version 1.0.37-13.2 for P01 (BCM96338)

[ 0.472000] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)I've loaded both 64kCFE and 128kCFE, but neither work, since they can't get a Flash Map (and the dmesg is identically to this one).
Now I'm compiling Kamikaze r25563 (I know its old, but to test for now) with some modifications in the board_brcm63xx and the corresponding Makefile to add my image. However these config is the same as the 6338W, so I don't expect any improvment.
What can I do to fix this?
Thanks!
