Hello All,
I think there might be an issue with the ART address offset in the Alfa
hornet board definition files in CC 15.05.
Alfa makes the hornet-ub and hornet-hsb (used in the Tube2h product)
boards which come in 8M and 16M flash versions. The openwrt make system
supports both flash models. However.. there is only one board definition
file for each of the hornet-us and tube2h boards.
mach-hornet-ub.c is used for both the 8M and 16M of flash models of the
hornet-ub board
mach-tube2h.c used in the 8M and 16M of flash models of the hornet-
hsb/tube2h product.
for the 8M models the ART partition starts at 0x00f7f0000 and 0x00ff0000
for the 16M versions.
However...
mach-horent-ub.c has an offset of 0x1fff0000 hardcoded for the ART offset.
here is a code snippet
u8 *art = (u8 *) KSEG1ADDR(0x1fff0000);
ath79_init_mac(ath79_eth1_data.mac_addr,
art + HORNET_UB_MAC0_OFFSET, 0);
ath79_init_mac(ath79_eth0_data.mac_addr,
art + HORNET_UB_MAC1_OFFSET, 0);
ath79_register_wmac(art + HORNET_UB_CALDATA_OFFSET, NULL);
similarly the tube2h board file has an offset of 0x1ff7f0000 hardcoded in
its board definition file file.
#define TUBE2H_ART_ADDRESS 0x1f7f0000
u8 *art = (u8 *) KSEG1ADDR(TUBE2H_ART_ADDRESS);
ath79_register_wmac(art + TUBE2H_CALDATA_OFFSET, NULL);
ath79_init_mac(ath79_eth0_data.mac_addr,
art + TUBE2H_LAN_MAC_OFFSET, 0);
Nowhere in the build system do I see where the ART offsets get modified
when building the firmware for as specific board model.
My concern is that without the correct offset the WiFI calibration (and
mac addresses) don't get initialized correctly.
Can anyone shed light on whether this is really a problem or if somewhere
behind the openwrt build machinery these offsets are magically adjusted
appropriately?
Thanks,
