Hi, I'm having some issue trying to talk to a chip over I2C.
The chip in question is the ATAES132
(https://cdn.sparkfun.com/datasheets/Dev/Beagle/Atmel-8760-CryptoAuth-ATAES132-Datasheet.pdf)
on the cryptocape. Up to yesterday I could send command and read response
packets from the Command memory register, but today the chip doesn't appear
anymore on the I2C bus.
root@beaglebone:~# i2cdetect -y -r 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- UU -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: *--* -- -- -- UU UU UU UU -- -- -- -- -- -- -- --
60: 60 -- -- -- 64 -- -- -- UU -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
It was showing at the address 0x50. Trying to read from this slave address
now gives me random bytes. Anyone has an idea on how to fix this ? Did I
brick the chip ?
