Dowload code into HSFB EVM

Knighty Nimp

All,

I bought UCD3138HSFB EVM and try to download code into EVM, we found the error as attached. 2112.Presentation1.pptx

-Open Device GUI(Version 1.8.325)

-Scan device in ROM mode, the GUI say "no ROM detect"

I notice that no LED indicate on EVM board(USB to GPIO should be OK as It's green LED )and not sure the EVM is ready to download the code? or I miss something on the EVM board.

Thanks.

anyone

Hi,

I believe the EVM is already loaded with firmware. Click "DEVICE_ID" and you'll find the device in program mode.

Hello,

I was downloaded my Firmware in the target via UCD3xxx & UCD9xxx Device GUI .
but I lost access to the ROM (ROM not detected) . The following figure shows you what you get when doing a Scan Device in ROM Mode

But when you click Scan For Device in Program Mode we get this:

At this stage, it is blocked it does not have the right to appoint another Firmware or the possibility of recovering the Flash program. It seems like I was be locked in Flash mode.

So , How can i get back to ROM mode

Regards
Thanks

Hi Abbadi,

Can you click "jump to ROM"? If you can't, there is a back door in the firmware:

At the beginning of main(), you should see something like this:

if(GioRegs.FAULTIN.bit.FLT2_IN == 1)
{
clear_integrity_word();
}

This means pull FLT2 high to clear the checksum and go back to ROM. You can check which IO you assigned and see if that works.

Regards,

Fan
