hi all,
i have some issues with an mcf5307 (coldfire, see my previous post of 38 Jul).
I am now suspecting of some differences in the toolchain.
Is there a specific gcc toolchain (or gcc version) required to build u-boot ?
I had good results using CodeSourcery Light (don't remember the exact version, something from 2009) for MCF5373 and MCF54455 in early 2010.
Unfortunately I am currently not working on it any more.
Best regards, Wolfgang
many thanks,
i have a very strange issue:
on a timer interupt i ger a vector 3 error:
_int_handler: // commeneted all, only rte left, exception in rte
rte
*** Unexpected exception *** Vector Number: 3 Format: 04 Fault Status: 4
PC: 00fe910a SR: 00002000 SP: 00ed8af0 D0: 00002c1b D1: 0000001b D2: 00400000 D3: 00ee8b76 D4: ffc12d08 D5: ffffffff D6: 00ffad57 D7: 00ee8b76 A0: 00ee8b76 A1: 00fe9604 A2: 00ee8bc6 A3: 00ffd400 A4: 00ff8167 A5: 00ffbb00 A6: 00ed8b48
there is nothing inside the interrupt handler, so there would be apparently any reason to get the exception on "rte", so my only suspect is about toolchain/compiler.
every help is welcome
Reagards, angelo
I found something interesting:
_int_handler: rts
seems to work, execution return to board_init_r, even if still the command console seems locked.
_int_handler: rte
generate the exception above.
Seems that @ SP there is the "next" return address instead of the vector/format/status values.
Any help is really appreciated.
