TMS320F28377S: DCSM Error.

Hello,

Can you provide more details on your flash programming flow? How many bits are you programming at a time? The dcsm.asm/dcsm.cmd memory sections are not aligned to 128-bit aligned addresses, so that could cause issues during programming. 

Best, 

Matt

first i upload flash kernel( provided by TI)
on successful hand shake i start uploading the hex file, 256-byte chunks max.
my normal code is uploading successful. but there is error following scnerio.

1. using dcsm_security_tool hex file. when i dont enable Zone1 header, LFU is updated successfully, but when i enable Zone1 header (on Fresh Mcu) LFU fails. i have attaced both filre

2. where i need to set 128-bit aligned addresses.

hex.files.rar

the following is the dcsm.cmd file which gives error

i enabled DCSM module in my code (which was successfully flashing via LFU), failed this time, i enabled pswdlock permanently and disabled CRClock. 
0x78010 turned FFF0. OTA faild and surprisingly reaming code is working only DCSM portion lfu failed

Hello,

Apologies I was travelling for business and didn't have time to assist E2E. I will look at this thread tomorrow.

Best,
