Increase code size region to 1 MB from default 512KB

Hi,

In our Dialog based hardware, I am trying to increase the FLASH_REGION_SIZE to 1 MB from the default 512KB as per the following link.

http://lpccs-docs.dialog-semiconductor.com/tutorial_da1469x_supporting_fw_images_bigger_than_512kb/Implementation.html

I am using SmartSnippets Toolbox version 5.0.14.3080.

In the SmartSnippets Toolbox, after I enter 0x5 (for 1MB code size) in CACHE_FLAG_REG, I don't see the screen with the title "Overwrite read-only words" which shows the address, where I can select Burn. I have attached the screen I am expecting but not seeing.

What do I need to do to get to this screen? Could this be the issue why the Burn is not happening.

Since I did not get this screen, I selected Burn on the next screen which is the OTP Header screen. But when I flash firmware greater than 512 KB, the board does not come up.I think the 0x5 setting in CACHE_FLAG_REG has not taken effect.

Could you please help. This is a little urgent.

Thanks and Regards,

Subramanyan

Hi Subramanyan,

Hi Subramanyan,

Could you please read the OTP Configuration Script? Can you see the CACHE_FLAG_REG entry at the bottom of the CS? Please share a screenshot.

Thanks, PM_Dialog

Hi PM_Dialog,

Hi PM_Dialog,

I have attached the OTP Config Script. Prior to this, I selected Add and set a value of 0x5 for the CACHE_FLASH_REG. I dont see this added to this.

Please let me know how I should fix this.

Thanks and Regards,

Subramanyan

Hi PM_Dialog,

Hi PM_Dialog,

Any solution for this. Do I need to uninstall and install SmartSnippets Toolbox and SmartSnippets Studio? Would that resolve the issue.

Thanks and Regards,

Subramanyan

Hi Subramanyan,

Hi Subramanyan,

The cli_programmer from SST v5.0.14 can be also used.

You can write in the OTP using:

> ./cli_programmer /dev/cu.usbserial-21200 write_otp 0x34A 2 0x50000050 0x000018F4 cli_programmer 1.26 Copyright (c) 2015-2019 Dialog Semiconductor Configuration from cli_programmer.ini file loaded. Using serial port /dev/cu.usbserial-21200 at baud rate 230400. done.

Thanks, PM_Dialog
