Hi, This is a follow-up post from the comment . In the l4t document, it is said that odm reserved fuses can be burned as follows. -o Sets odm_reserved to the specified value. The value must be a quoted series of eight 32-bit HEX numbers such as: “0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX 0xX…

Hi TakenoriSato, Please read odm reserved value from: # cat /sys/devices/7000f800.efuse/7000f800.efuse:efuse-burn/reserved_odm<b>X</b> X for 0~7 (reserved_odm0 ~ reserved_odm7).

Thanks for the suggestion. But no luck. $ sudo ./odmfuse.sh -i 0x21 -c PKC -k ../emi_pkc.pem -o 0x0000000000000000000000000000000000000000000000000000000100000000 *** Calculating HASH from keyfile /home/tsato/Desktop/l4timages/Nano/L4T32.3.1/emi_pkc.pem ... done PKC HASH: 0x78e352f7bb4cc4f0ea430b7…

Here’s the result of a TX2 carrier board, whose secure boot was successfully enabled. Note that the running OS is L4T 32.2.3. $ sudo ./tegrafuse.sh [sudo] password for nvidia: Unsupported fuse: device_key Unsupported fuse: jtag_disable odm_lock : 0x00000000 odm_production_mode : 0x00000000 Unsup…

Hi, Do you use Nano production module? We have tried the command and it works well.

TakenoriSato, "ODM_RESERVED and ODM_LOCK fuses are still writable until the ODM_LOCK bit is burned => Fuse Spec document states more clear so you can refer to that. ODM_RESERVED fuses is reserved for SW usage so can still be programmed after ODM_PRODUCTION_MODE fuse bit is burned. However, the fir…

Yes. Can you show what command do you use with which tool exactly? Thanks for the information. So, I will avoid using 1 as a test value. When you say FUSE_RESERVED_ODMn, how is n counted? For example, in my example, I have tried to set 1 as “0x00000000 0x00000000 0x00000000 0x00000000 0x00000000…

Thanks. That’s exactly the same as my first post of this thread. Good to hear that 1 is not on the FUSE_RESERVED_ODM1. Here’s the result. I can not verify. But the odmfuse.sh command has never succeeded. $ sudo ./tegrafuse.sh arm_jtag_disable : 0x00000000 odm_lock : 0x00000000 odm_production_…

Hi, #2 is what we have verified working on Nano production module. It is not expected you hit error in running same command. Do you by accident you change emi_pkc.pem? The error now is [ 1.7118 ] Failed to burn fuses as per fuse info blob, Error:1179996997 [ 1.7331 ] 0100cdaa: Failed to proces…

Thanks for looking at this. The hash from the first command is the same as the second one as two hash values are the same as below. First $ sudo ./odmfuse.sh -i 0x21 -c PKC -k ../emi_pkc.pem -o "0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000000 0x00000001 0x00000000" [sudo] passw…

Hi TakenoriSato,

Please try below command:

$ sudo ./odmfuse.sh -i 0x21 -c PKC -k ../emi_pkc.pem -o 0x0000000000000000000000000000000000000000000000000000000100000000
