a preliminary question to make sure i'm on the right track in terms of adding panda ES support. i have a couple panda boards -- an earlier EA3 revision (OMAP 4430), and a panda ES (OMAP 4460). using a regular panda config and build, i can boot the earlier board: barebox 2012.02.0-00090-g675502d-dirty (Feb 8 2012 - 17:03:18) Board: Texas Instrument's Panda PandaBoard Revision: 003 ehci@ehci0: USB EHCI 1.00 Malloc space: 0x8d000000 -> 0x8effffff (size 32 MB) Stack space : 0x8cff8000 -> 0x8d000000 (size 32 kB) Open /boot/bareboxenv No such file or directory no valid environment found on /boot/bareboxenv. Using default environment running /env/bin/init... so that's a good sign. and the Revision number of 3 matches what i see here: http://omappedia.org/wiki/PandaBoard_Revisions#PandaBoard_Revision_History so far, so good. now if i use precisely the same files for my ES, i get absolutely no output. none. but that's not surprising since in the omap4_generic.c file, i read: unsigned int omap4_revision(void) { unsigned int chip_rev = 0; unsigned int rev = cortex_a9_rev(); switch(rev) { case 0x410FC091: return OMAP4430_ES1_0; case 0x411FC092: chip_rev = (readl(OMAP44XX_CTRL_BASE + 0x204) >> 28) & 0xF; if (chip_rev == 3) return OMAP4430_ES2_1; else if (chip_rev >= 4) return OMAP4430_ES2_2; else return OMAP4430_ES2_0; } return OMAP4430_SILICON_ID_INVALID; } i'm assuming the fact there is *no* checking for an OMAP4460 is the reason i get nothing, is that a reasonable assumption? i'll post more detail later about what i'm going to try but given that the above function does not take into account the OMAP4460-based ES boards, would that cause a complete lack of output at boot time? thanks. rday -- ======================================================================== Robert P.
