hmm well thats your opinion

just curious: do you think "tunavids" by chrism was also a waste of time for him? basically it's the same thing

what i need from the arm7 isn't something everyone else will be in need for: 1) lets assume arm7 decodes a raw mp3 stream with a helix decoder, a bug appears and arm7 sends a fifo message to arm9 with the exact problem while decoding. (i don't know if there is a way to do this with MM now) 2) lets ...

i think there is a minor typo in the fifocommon.h at: typedef enum { FIFO_PM = 0, FIFO_SOUND = 1, FIFO_SYSTEM = 2, FIFO_RSDV_01 = 3, FIFO_RSVD_02 = 4, FIFO_RSVD_03 = 5, ... Where "FIFO_RSDV_01" should have been "FIFO_RSVD_01" EDIT: doesn't matter at all because this channel identifier will never get ...

well the march flag was the culprit, c
double checked it even without irqinit.

and yes, usually i would use the default arm7 core but i need my own code in arm7 for special tasks (i.e. when arm9 is busy) with special fifo callbacks

found the problem :-) So for anyone else interested: In my very old project i had the wrong cpu architecture selected in the arm9 makefile was ARCH := -marm -mthumb-interwork which has to be changed to this, so the fifo works: ARCH := -mthumb -mthumb-interwork additionally the arm9 main shouldn't ...

Hi there, i have a little Problem understanding the new FIFO based arm7<->arm9 communication. I tried to send a simple message to arm7 (from arm9) and respond back to arm9 as soon as the message arrives. This should be very straightforward, especially since the wifi init does work in the exact same ...
