Hello, Sasha. It seems I've fixed all according your remarks instead of one question. 10.04.2014 09:16, Sascha Hauer пишет: > > As suggested in my last mail: > > Do we need this tool at all?

For example, I'm trying just to add bool parameter in imx_ocotp_probe(), for additional FUSE write protection: > if (IS_ENABLED(CONFIG_IMX_OCOTP_WRITE)) { > dev_add_param_bool(dev, "permanent_write_enable", > NULL, NULL, &priv->write_enable, NULL); > } and check priv->write_enable instead of CONFIG_IMX_OCOTP_WRITE in write function. But how to set permanent_write_enable to 1 in barebox shell? As I understand, it should be something like ocotp0.permanent_write_enable=1, but I don't see any similar. If I add > add_generic_device("ocotp", 0, NULL, MX6_OCOTP_BASE_ADDR, 0x2000, > IORESOURCE_MEM, NULL); to board.c, I see something like 21bc000.ocotp.write_enable= available, but 21bc000.ocotp.write_enable=1 or 21bc000.ocotp.write_enable=0 doesn't work, saying "No such file or directory". Also, as I understand, it's an incorrect in field of using devicetree. One more question: is there any way in barebox shell to write to character device with offset? For example, ocotptool just writes (reads) 8 bytes to ocotp cdev with offset 0x22*4 (MAC offset). How to do it from shell? -- With regards, Uladzimir Bely. _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
