Hi, I am running ppc440 with linux kernel version 2.4 If I reboot the ppc440 in middle of a read transaction from a slave say( at the 3rd clock pulse for example) then somehow ppc440 is hung.
Basically when it comes up it sees that data line held low. How does the powerpc deal with this situation.? >From the i2c bus trace it looks like in this situation ppc440 keeps issuing the clock pulses until the data line SDL is released by the slave but following that the SCL line is held low by ppc440 and is never released or set to IDLE? Is this the expected behaviour if the SDL is held low when the ppc440 comes up. Is there anyway I can fix this in the ppcboot code. Please let me know. Any help appreciated.
