Hi guys, I have a beaglebone and would like to read the content of thee eeprom from uboot. i2c probe gives me the following: U-Boot# i2c probe Valid chip addresses: 00 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 30 31 32 33 34 35 36 37 38 39 3A 3B 3C 3D 3E 3F 40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F 50 51 52 53 54 55 56 57 58 59 5A 5B 5C 5D 5E 5F 60 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 7B 7C 7D 7E 7F U-Boot# i2c dev Current bus is 0 -Boot # i2c read 0 0x24 4 i2c - I2C sub-system
Usage: i2c crc32 chip address[.0, .1, .2] count - compute CRC32 checksum i2c dev [dev] - show or set current I2C bus i2c loop chip address[.0, .1, .2] [# of objects] - looping read of device i2c md chip address[.0, .1, .2] [# of objects] - read from I2C device i2c mm chip address[.0, .1, .2] - write to I2C device (auto-incrementing) i2c mw chip address[.0, .1, .2] value [count] - write to I2C device (fill) i2c nm chip address[.0, .1, .2] - write to I2C device (constant address) i2c probe - show devices on the I2C bus i2c read chip address[.0, .1, .2] length memaddress - read to memory i2c reset - re-init the I2C Controller i2c speed [speed] - show or set I2C bus speed
What is the right command to read from an address?
