I have some questions...about secure jtag mode
My development board is a IMX6 Sabrelite(boundarydevices).
I don't know how to configure secure jtag mode.
00 - JTAG enable mode (Default)
01 - Secure JTAG mode
11 - No debug mode
searched below files but can not find out it.
- Configuring Secure JTAG for the i.MX 6 Series Family of Applications Processor.pdf
- i.MX 6Dual_6Quad Multimedia Applications Processor Reference Manual (REV B).pdf
in the Secure JTAG doc, i could see "/sys/fsl_otp/HW_OCOTP_CFG5"> Burn JTAG_SMODE =01 fuse</CMD>".
but i also find out "echo 0x2 > HW_OCOTP_CFG5" command to configure SEC_CONFIG to close mode in how to enable hab doc.
Then both use same HW_OCOTP_CFG5 bit...
please help me.
