TMS570LS3137: Flash ECC Generation from Linker

Hello,

I tried to generate the flash ECC using linker based on the following post and articles:

TMS570LS3137 - Linker Generated ECC - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

7.1. Linker Generated ECC — Hercules Safety MCUs Documentation

My Linker command file is as below:

MEMORY
{
    VECTORS (X)  	: origin=0x00000000 length=0x00000080 vfill = 0xffffffff
    KERN_FUNC (RX)	: origin=0x00000080 length=0x0000FF80 vfill = 0xffffffff
    FLASH0  (RX)	: origin=0x00010000 length=0x00010000 vfill = 0xffffffff
    STACKS  (RW) 	: origin=0x08000000 length=0x00001800
    KERN_DATA (RW) 	: origin=0x08001800 length=0x00000800
    RAM     (RW)	: origin=0x08002000 length=0x0003E000
    VECTORS_ECC  	: org = 0xf0400000  len = 0x10
                   ECC = { input_range = VECTORS, algorithm = eccalgo, fill = true }

   KERN_FUNC_ECC  	: org = 0xf0400010  len = 0x1FF0

                   ECC = { input_range = KERN_FUNC, algorithm = eccalgo, fill = true }
  FLASH0_ECC  	: org = 0xf0402000  len = 0x2000

                   ECC = { input_range = FLASH0, algorithm = eccalgo, fill = true }
 }
ECC
{

   eccalgo : address_mask = 0x003ffff8

             hamming_mask = R4

             parity_mask  = 0x0C

             mirroring    = F021

}

my debug settings are as follow:

I have the flash ECC check enabled in Halcogen, and when I try to flash the generated binary from the CCS, I have the ESM module triggering the nError output. 

I tried by flashing it from Uniflash, it has the same behaviour.

I guess there is some mistake in my linker file? could you please provide some feedback regarding this?

Thanks.
