Hi All, We are working on a board based on the BBB design and in our latest revision we have no Ethernet chip on board. During boot, I get a Kernel panic:
davinci_mdio 4a101000.mdio: davinci mdio revision 1.6 [ 10.739305] davinci_mdio 4a101000.mdio: no live phy, scanning all [ 10.745901] davinci_mdio: probe of 4a101000.mdio failed with error -5 [ 10.752865] Detected MACID = d0:ff:50:b1:b7:3e [ 10.757374] Unhandled fault: external abort on non-linefetch (0x1008) at 0xe089c000 [ 10.765550] Internal error: : 1008 [#1] SMP THUMB2 [ 10.770538] Modules linked in: [ 10.773724] CPU: 0 Not tainted (3.8.13-bone59 #1) [ 10.779000] PC is at cpsw_probe+0x37e/0x9fc [ 10.783353] LR is at ioremap_page_range+0x8d/0x11c [ 10.788347] pc : [<c03160d2>] lr : [<c0243e2d>] psr: a0000033 [ 10.788347] sp : df071df8 ip : 4a100000 fp : df071e30 [ 10.800304] r10: 00000002 r9 : e089c000 r8 : 00000000 [ 10.805742] r7 : 00000000 r6 : df0d3400 r5 : 00000000 r4 : de2f6000 [ 10.812543] r3 : 00000000 r2 : e089d000 r1 : 4a100e13 r0 : e089c000 [ 10.819340] Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA Thumb Segment kernel [ 10.827138] Control: 50c5387d Table: 9e34c019 DAC: 00000015 [ 10.833125] Process swapper/0 (pid: 1, stack limit = 0xdf070240) [ 10.839385] Stack: (0xdf071df8 to 0xdf072000) My research suggests that this is due to the Ethernet chip not being present. During Kernel building I have removed Device Drivers -> Network Device Support -> Ethernet Driver Support -> TI devices, however this does not seem to make any difference at all? Has anybody got any ideas as to what I might try?
