Hi
I'm trying to setup nand support for an omap3 board for linux-next
(next-20130417). This is my approach so far:
+&gpmc {
+ ranges = <0 0 0x30000000 0x1000000>;
+ nand@0,0 {
+ reg = <0 0 0xff>; /* <- ? not sure about that */
+ nand-bus-width = <16>;
+ ti,nand-ecc-opt = "bch8";
+ /* no elm on omap3 */
+
+ gpmc,time-para-granularity = <0>;
+ gpmc,mux-add-data = <0>;
+ gpmc,device-nand = <1>;
+ gpmc,device-width = <2>;
+ gpmc,wait-pin = <0>;
+ gpmc,wait-on-write = <0>;
+ gpmc,wait-on-read = <0>;
+ gpmc,burst-length= <4>;
+ gpmc,sync-write = <0>;
+ gpmc,burst-write = <0>;
+ gpmc,sync-read = <0>;
+ gpmc,burst-read = <0>;
+ gpmc,burst-wrap = <0>;
+ gpmc,cs-on-ns = <0>;
+ gpmc,cs-extra-delay = <0>;
+ gpmc,cs-rd-off-ns = <0x14>;
+ gpmc,cs-wr-off-ns = <0x14>;
+ gpmc,adv-on-ns = <0>;
+ gpmc,adv-extra-delay = <0>;
+ gpmc,adv-rd-off-ns = <0x14>;
+ gpmc,adv-wr-off-ns = <0x14>;
+ gpmc,oe-on-ns = <0x1>;
+ gpmc,oe-extra-delay = <0>;
+ gpmc,oe-off-ns = <0xF>;
+ gpmc,we-on-ns = <0x1>;
+ gpmc,we-extra-delay = <0>;
+ gpmc,we-off-ns = <0xF>;
+ gpmc,rd-cycle-ns = <0x14>;
+ gpmc,wr-cycle-ns = <0x14>;
+ gpmc,access-ns = <0xC>;
+ gpmc,page-burst-access-ns = <0x1>;
+ gpmc,bus-turnaround-ns = <0x0>;
+ gpmc,cycle2cycle-diffcsen = <0x0>;
+ gpmc,cycle2cycle-samecsen = <0x1>;
+ gpmc,cycle2cycle-delay-ns = <0xA>;
+ gpmc,wr-data-mux-bus-ns = <0xF>;
+ gpmc,wr-access-ns = <0x1F>;
+
+ #address-cells = <1>; /* <- ? not sure about that */
+ #size-cells = <1>; /* <- ? not sure about that */
+ };
+};
+
I took the GPMC NAND config from u-boot where it's working correct.
Without the additional nand approach from above, the board is working
more or less fine. But with this patch I do get the following crash:
