Tool/software:

Hi,

I am trying to flash our AM335x custom board using USB RNDIS and CCS Uniflash Version 3.4. All the images are being flashed, but the Status view is not showing the correct progress and status.

Here is the sequence that I followed.

1. Loading u-boot-spl-restore.bin and u-boot-restore.img

2. Loading MLO.byteswap and u-boot.img image files over TFTP and flash them to SPI Flash

3. Loading the zImage (with RAMFS) and dtb files via TFTP and booting.

4. After booting the kernel and attaching the filesystem, the fetcher script pulls the flasher script over TFTP.

5.Run the flasher script to create the eMMC partition, and transfer the filesystem and kernel to the partition.

Please let me know where I am going wrong, and also if anyone can help me with detailed documentation.

Hi,

Here is the Uniflash documentation for AM335x:

I followed the same steps described in the link you mentioned, but it still isn’t showing 100% in the Progress and Status sections. Sometimes it shows 27%.

Hi Vipin,

I currently don't have access to a Windows PC to validate this, but do you use v3.4.0 or v3.4.1?

v3.4.1 is the last version which supports AM335x devices.

v3.4.1 is the version we are using. Can you provide some information on how CCS Uniflash handles the progress bar? Is there any communication that needs to happen from the AM335x to CCS Uniflash, or does CCS automatically update after transferring the respective files over TFTP?

Hi Vipin,

I am routing your query to our dev team for comments.

Vipin,

UniFlash v3.4.1 was released a while back, so it will take a bit of time to look up the code and provide some additional information on how the progress bar is implemented. I'll let you know if I find any information on this.

You mentioned that it sometimes shows 27%. Does it show other values as well, or is it always 27% for your case?

Thanks,

Ricky
