CONFIGURATION OPTIONS/SETTINGS ---------------------------------- - -1.1 CONFIG_MX51_PLL_ERRATA: Workaround for i.MX51 PLL errata. - This option should be enabled by all boards using the i.MX51 silicon - version up until (including) 3.0 running at 800MHz. - The PLL's in the i.MX51 processor can go out of lock due to a metastable - condition in an analog flip-flop when used at high frequencies. - This workaround implements an undocumented feature in the PLL (dither - mode), which causes the effect of this failure to be much lower (in terms - of frequency deviation), avoiding system failure, or at least decreasing - the likelihood of system failure. - -1.2 CONFIG_SYS_MAIN_PWR_ON: Trigger MAIN_PWR_ON upon startup. - This option should be enabled for boards having a SYS_ON_OFF_CTL signal - connected to GPIO1[23] and triggering the MAIN_PWR_ON signal like in the - reference designs. - -2. CONVENTIONS FOR FUSE ASSIGNMENTS ------------------------------------ - -2.1 MAC Address: It is stored in the words 9 to 14 of fuse bank 1, using the - natural MAC byte order (i.e. MSB first). - - This is an example how to program an example MAC address 01:23:45:67:89:ab - into the eFuses. Assure that the programming voltage is available and then - execute: - - => fuse prog -y 1 9 01 23 45 67 89 ab - - After programming a MAC address, consider locking the MAC fuses. This is - done by programming the MAC_ADDR_LOCK fuse, which is bit 4 of word 0 in - bank 1: - - => fuse prog -y 1 0 10 |
