TDA4VM: DFU Failure with SDK 7.1

Part Number: TDA4VM

Hello,

I'm trying to move our project from SDK_7.0 to SDK_7.1.

I got a problem with DFU.

I tried executing u-boot and downloading tiboot3.bin, sysfw.itb, tispl.bin and u-boot.img in order with DFU.

However, tiboot3.bin was completed and sysfw.itb was failed with SDK_7.1.

I fond that dfu_bufsiz in j721e_evm.h was increase from 0x20000 to 0x40000 at SDK_7.1.

I modified it to 0x20000 as SDK_7.0 and I ended up downloading everything.

Is there a reason dfu_bufsiz was changed to 0x40000?

The small buffer(0x20000) for DFU can make side effects?

Hi Reuben,

I just looked at the commit that changed this, this was done for another platform but should be compatible with TDA4VM also. Let me check more on this and I will respond with the details.

Karan

Hi, Karan.

Thank you for your reply.

I don't think sysfw.itb cases this problem because it occurred before sysfw.itb was downloaded to the target board through DFU.

Best regards.
