Everything I see online tells me to cat a node like
/sys/bus/i2c/devices/1-0057/eeprom, but that doesn't seem to exist. This is for
my custom cape. I just installed the EEPROM IC at address 0x57, and I think the
OS is finding it:
[ 3.718888] bone_capemgr bone_capemgr: Baseboard:
'A335BNLT,00C0,3214BBBK4221'
[ 3.718924] bone_capemgr bone_capemgr:
compatible-baseboard=ti,beaglebone-black - #slots=4
[ 3.778342] bone_capemgr bone_capemgr: slot #0: No cape found
[ 3.838333] bone_capemgr bone_capemgr: slot #1: No cape found
[ 3.898333] bone_capemgr bone_capemgr: slot #2: No cape found
[ 3.928169] bone_capemgr bone_capemgr: Invalid signature 'ffffffff' at slot 3
[ 3.935464] bone_capemgr bone_capemgr: slot #3: No cape found
[ 3.941370] bone_capemgr bone_capemgr: initialized OK.
But I can't figure out how to read (or write) the contents, since the OS driver
has it ("Error: Could not set address to 0x57: Device or resource busy").
So, I'm trying to read and write via sysfs, but I don't see the node. I'm on
kernel 4.1.6-ti-r15.
TIA,
