BT_FUSE_SEL EBOOT

[gavinwalker]

Could someone tell me how I programatically set BT_FUSE_SEL. I might be missing something but in the SBR register at +0x460 from the datasheets it is only read only. I appreciate it can only be set the once to change to boot from the fuses but I'm not sure how this works? I would like to start eboot note eboot not uboot, from one boot source, this then writes the fuses so next reboot it will then start from the final source. Or is this something that can only be done by the mfg tool.

Hi Gavin

fuses can be programmed in UBoot

https://community.freescale.com/docs/DOC-95458

or using SDK with jtag

"MX6_PLATFORM_SDK "

https://community.freescale.com/docs/DOC-94139

Boot Mode register (SBMR) contains bits that reflect the status of

Boot Mode Pins of the chip, they are read by processor during boot and can not be written.

Best regards

Hi Igor,

Thank you for your reply I will have a look at that. Eboot doesn't appear to come with the imxotp as uboot does so I suspect that we will have to look at the mfg tool
