What about to use a u-boot environment to select the display ? Could be a better solution for you ? You can then have a single u-boot image managing both displays. I did in this way for the mt_ventoux board (board/mt_ventoux/mt_ventoux.c), maybe can this help ?
Sounds good. I tried this approach.
However, when I try to manipulate the env var I am not able to boot:
U-Boot 2012.10-09480-g6b08fc3-dirty (Oct 23 2012 - 15:24:03)
Board: MX53 LOCO I2C: ready DRAM: 1 GiB ...
These are my simple changes (just to show the issue I am facing):
--- a/board/freescale/mx53loco/mx53loco.c +++ b/board/freescale/mx53loco/mx53loco.c @@ -471,6 +471,18 @@ void lcd_iomux(void) void lcd_enable(void) { int ret = ipuv3_fb_init(&claa_wvga, 0, IPU_PIX_FMT_RGB565); + char *e; + + e = getenv("panel"); + + if (e != NULL) { + if (strcmp(e, "claa") == 0) + printf("Panel is claa\n"); + + if (strcmp(e, "seiko") == 0) + printf("Panel is seiko\n"); + } + if (ret) printf("LCD cannot be configured: %d\n", ret); }
Any ideas?
Thanks,
