AEDHi Team,

I am using boot_emac_flash for firmware upgrade , my current requirement is to decrypt the binary before downloading into external RAM Via EPI module,

I integrated the code but how and where to add the interrupt for AES 128 bit decryption and EPI0 module pins in bl_startup_ccs.s file to enable it

can you please suggest how add these interrupts in bl_startup_ccs.s file

Hi,

I'm currently on vacation for the entire week. I will reply your question when I have time later today. Please expect delayed response.

Hi,

Please bear in mind that TM4C1294NCPDT does NOT have AES feature. Refer to the TM4C Product Selection Guide for the part numbers that support AES. See below.

Let's suppose you are using a part number that supports AES. In this case, the AES interrupt will be mapped to vector number 111. See below.
