Make sure ECC is calculated and is part of the Image before programming

Note: If ECC locations are not programmed correctly device might be locked permanently.

I saw this warning and how can i sure ECC locations are correct?

Hi Rahmi,

What it means is that, before flashing the code we should need to make sure the "Auto ECC generation"

If we are using CCS then this option will be at below configuration:

If you are using uniflash then:

If we make sure this then our executable will have the ECC.

After locking JTAG, how can we unlock it again when i want to read data?

Thanks & regards.

Please refer below APP note to understand the same:

Thanks for your reply,

I read that pdf before and I understand how to unlock AJSM with CCS, but Is there any way to unlock it without using CCS like using some command for unlock?

Thanks & regards.

I don't have any idea how we can do without CCS.

I need to check with some expert for this.
