code signing tool

praveen_bharath — Thu, 21 Feb 2019 17:12:18 GMT

Hello,

I am unable to sign my product code using the CST. The script fails while generating the CSF binary with an undefined error, and always its on line 2 or before.

keys$ ../linux32/bin/cst --o csf-uboot.bin --i csf-uboot
error: line 2: syntax error

I understand the cst tool has a limitation that requires the command be run from the keys directory. I have had the u-boot.imx image moved to the keys directory. But that hasnt helped. I am missing something here?

Any help is appreciated.

Thanks

Hello,

I am past that issue. I am now able to build the csf file, sign the boot loader image. I flash using the manufacturing tool. However there is something wrong due to which the HAB is disabled during boot.

Here is the CSF I am using (copied from AN4581). I am not sure if I can use the address in the example straight in my product. I have seen people posting their CSFs in the forum with all kinds of addresses and thats the reason for my doubt. The part we are using is IMX7 Dual and I used the linux32 bit version of cst to sign my image as I understand the IMX7 is a 32 bit device.

I do not have access to that document. How do I get it?

I need information on all the config options for the file.
