CCSTUDIO: CCS Uniflash, AM335x

Tool/software:

Hello,

I'm trying to flash our custom AM335x board using USB RNDIS and CCS Uniflash Version 3.4.1. Although the images are being successfully flashed, the Status view is not displaying the correct progress and status.

Here’s the sequence I followed:

Loaded u-boot-spl-restore.bin and u-boot-restore.img.
Transferred MLO.byteswap and u-boot.img over TFTP and flashed them to SPI Flash.
Loaded the zImage (with RAMFS) and dtb files via TFTP and booted the system.
After booting the kernel and attaching the filesystem, the fetcher script retrieves the flasher script over TFTP.
Executed the flasher script to create the eMMC partition and transfer the filesystem and kernel to that partition.

Could you help me identify where I might be going wrong? Also, if there's any detailed documentation available, I'd appreciate it.

Hi Pooja,

The user's guide for this feature is available here: https://software-dl.ti.com/processor-sdk-linux/esd/AM335X/09_01_00_001/exports/docs/linux/Foundational_Components/Tools/Flash_Tools.html#sitara-uniflash

As for the progress issue, are you seeing it stuck on 27% every time, or does it show different values each time you flash?

Thanks,

Ricky

Hi Ricky,

It gets stuck at 27% every time.

Can you explain how CCS Uniflash manages the progress bar? Does the AM335x need to communicate with CCS Uniflash during this process, or does CCS automatically update the progress after transferring the files via TFTP?

Thanks for the info. I will get back to you once I have more specifics on how the progress bar was implemented.

Thanks.
