| Description: | |
| Value representing the can_id of mailbox 0. | |
| Default: 0x7ff (standard frame) | |
| Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in | |
| "AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the | |
| contents of mailbox 0 may be send under certain | |
| conditions (even if disabled or in rx mode). | |
| The workaround in the errata suggests not to use the | |
| mailbox and load it with an unused identifier. | |
| In order to use an extended can_id add the | |
| CAN_EFF_FLAG (0x80000000U) to the can_id. Example: | |
| - standard id 0x7ff: | |
| echo 0x7ff > /sys/class/net/can0/mb0_id | |
| - extended id 0x1fffffff: | |
| echo 0x9fffffff > /sys/class/net/can0/mb0_id |
