LP-AM243: Switching bootmode for MCU AM243x by using *.js file

Kathiravan Palani

Prodigy 95 points

Part Number: LP-AM243

Hi,

I'm using LP-AM243x, I tried switching UART mode and OSPI mode manually both are working fine.

Now I'm trying to Switch the bootmode by using *.js (change_boot_mode.js) in CCS Scripting console.

I tried writing various bootmode values in 0x78100000 location and executed the .*js.

from logs I can see that Bootmode is selected but after that I'm getting error mentioned below,

Getting log like this:

js:> loadJSFile ("C:/ti/mcu_plus_sdk_am243x_08_05_00_24/tools/ccs_load/am243x/change_boot_mode.js")
Connecting to MCU Cortex_R5_0!
Current Boot Mode is 120
Partition Unlocked..
OSPI Boot Mode Selected
Error writing memory: Errors during memory.writeData(): Address: 0x43018170 Error: 0x80000 (C:\ti\mcu_plus_sdk_am243x_08_05_00_24\tools\ccs_load\am243x\change_boot_mode.js#207)

Thanks in advance

Hi Kathiravan Palani,

Can you confirm what type of device do you have ? Use the following FAQ for the same.

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1170785/faq-mcu-plus-sdk-am243x-how-to-identify-if-the-device-is-gp-device-or-hs-device

If you have a GP device, and the boot mode is DEV BOOT MODE, this should have worked.

But if you have a HS-FS device, then you need to use load_dmsc_hsfs.js when your device is in DEV BOOT MODE. Like this -

https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_05_00_24/exports/docs/api_guide_am243x/EVM_SETUP_PAGE.html#autotoc_md31

https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_05_00_24/exports/docs/api_guide_am243x/HSFS_MIGRATION_GUIDE.html#CCS_BOOT_HS_FS

After the load_dmsc_hsfs.js is called, you can call the script to change the boot mode of the device.

Hi Aakash,

I'm using LP-AM243x which is GP type device.

I checked switch configuration for dev boot mode in launch pad user guide, I couldn't find that.

Can you tell me how to select dev boot mode in launch pad AM243x?

Thank you

Hi Kathiravan Palani,

The device Dev Boot mode and No Boot mode are same for LP devices.

Hi Aakash,

Log which I mentioned also shows that "current bootmode is 120" which is dev bootmode as per *.js file.

Even though getting the same error.

Hi Kathiravan Palani,

Let me try the same on my end. I am thinking maybe your device is not exactly GP.

Hi Kathiravan Palani,

It is working on my end. I see the boot mode changed by entering the value 1 i.e. UART boot mode.

Also the Tera Term shows the print -

Is this not your observation ?

Hi Aakash,

As of now I'm writing bootmode value in 0x78100000 address using memory browser window in CCS. Is there any way to do it without using CCS?
