**** BEGIN LOGGING AT Wed Aug 23 03:00:01 2017 Aug 23 11:40:36 I want to write a custom i2c driver for the default eeprom provided in the BBB. using i2c.h will do the job or do i require to study other stuffs. I am BBB with kernel 4 Aug 23 11:44:26 uhh, a custom driver for the eeprom? Aug 23 11:44:43 yes Aug 23 11:44:58 i want to read a byte from eeprom. Aug 23 11:45:56 you can read the eeprom via /sys/bus/nvmem/devices/0-00500/nvmem Aug 23 11:46:29 there is absolutely no need to manually perform i2c transactions for that Aug 23 11:47:06 this for kernel driver exercise. Aug 23 11:48:52 ah Aug 23 11:51:44 i cannot locate /sys/bus/nvmem/ Aug 23 11:52:03 what kernel version? Aug 23 11:52:50 4.11.0 Aug 23 11:53:36 i can find /sys/bus/i2c/devices/0-0050/ but this is not having nvmem Aug 23 11:54:11 you're not using one of the standard kernels for bbb ? (-bone or -ti) Aug 23 11:56:27 i guess nope. how can i check ? Aug 23 11:59:12 the presence of -bone or -ti in the kernel version (e.g. 4.9.27-bone4) as given by uname -r and also appearing in the name of the kernel package (e.g. linux-image-4.9.27-bone4) Aug 23 11:59:55 if you're using some oddball kernel then maybe CONFIG_NVMEM isn't enabled, which would explain the absence of /sys/bus/nvmem Aug 23 12:00:07 # uname -r 4.11.0 Aug 23 12:00:20 uname -r gives 4.11.0 Aug 23 12:00:25 and nothing else Aug 23 12:00:52 okay, i will enable CONFIG_NVMEM Aug 23 12:07:45 okay, now i am able to locate nvmem Aug 23 12:08:55 there is nothing inside /sys/bus/nvmem/devices/ Aug 23 12:09:01 totally empty Aug 23 12:17:26 I want to write a custom i2c driver for the default eeprom provided in the BBB. using i2c.h will do the job or do i require to study other stuffs. I am BBB with kernel 4.11.0 Aug 23 13:00:31 I want to write a custom i2c driver for the default eeprom provided in the BBB. using i2c.h will do the job or do i require to study other stuffs. I am BBB with kernel 4.11.0 Aug 23 17:42:19 Got some BBB's from Arrow and they say Rev C2 on the board, but http://elinux.org/Beagleboard:BeagleBoneBlack#Board_Revisions_and_Changes only lists up to a rev C. It doesn't appear to be the industrial-temp version. Any idea what might've changed in C2? Aug 23 18:32:36 I could be mistaken, but that's probably a revision of the pcb and not the product as a whole Aug 23 18:32:58 I have some from a while back that had like "Rev B6" on them Aug 23 18:49:10 (it was raised, inkless lettering on the pcb) Aug 23 20:14:13 Hi! Is there a known issue with beagle board (green) and some SD cards? It seems that the board can boot from but not write to the card. At least all files in /var/log are dated 19th of March. Aug 23 20:15:38 I am trying to log in via ssh but always get "Permission denied, please try again." when using the default user:pw (debian:temppwd) Aug 23 20:38:41 Okay, interesting. Login over ip4 when BB gets an IP over DHCP works. ipv6 link local does not Aug 23 21:21:02 Does the beaglebone black rev c support Micro SDHC cards? Aug 23 21:36:22 yes Aug 23 21:37:22 there is nothing really special. the differences between HC, XC, etc are in 'mandatory filesystem' and faster modes, the basic modes work just fine on all Aug 23 21:50:23 Alright, thanks for the help **** ENDING LOGGING AT Thu Aug 24 03:00:00 2017
