strange behavior with i2c on raspberry pi 4
Hello,
i have a raspi 4 with a RTC. Since some days I have a problem with the i2c.
The RTC is not found anymore.
So i disconnect the RTC and do a i2cdetect -y 1 and it looks like:
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: 08 09 0a 0b 0c 0d 0e 0f
10: 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f
20: 20 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f
30: -- -- -- -- -- -- -- -- 38 39 3a 3b 3c 3d 3e 3f
40: 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: 60 61 62 63 64 65 66 67 68 69 6a 6b 6c 6d 6e 6f
70: 70 71 72 73 74 75 76 77
No i2c device is connected.
uname -a
Linux counter 6.1.0-18-arm64 #1 SMP Debian 6.1.76-1 (2024-02-01) aarch64
GNU/Linux
What's wrong there?
Any ideas?
best regards
