First Time Programming - T1020

[hozefabharmal]

I have a new board designed based on T1040rdb (having T1020 in

my design).

(CPLD "EPM570" was programmed successfully)

While trying to program the board for the very first time, I am

seeing the below error

---------------------------------------

Error:  Connect Failed.

Failed to correctly configure the JTAG chain(CCSProtocolPlugin)

Error: Connect Failed.

---------------------------------------

The screenshot is attached in the mail.

Another thing I observed is that the ASLEEP LED is on.

I have also set the jumper for the first time programming

requirement "VCORE_HOT_N", with or without it the issue is same.

Is there any other setting required for the first time programming?

How to approach debugging this problem.

Hi Hozefa

This may not be related but I wonder how you are providing RCW for

your SoC. Do you have an hard-coded RCW that is supplied, e.g.

from your dip switches and CPLD ? The reason I am asking if your

design configuration expects to read RCW from your flash which is

empty initially it won't boot and JTAG communication will fail soon after.

Hope this helps

Hi Sinan,

Thanks for suggestion.

Yes, I am providing it  through DIP switch.

I have tried all possible combination like programming NAND as well NOR flash but the results are same.

Hi Hozefa

Does your DIP switch configuration provide

a hard-coded RCW as rcw_src ? Please

note that if your DIP switch only allows

loading RCW from external source (such

as NOR, NAND, SD, SPI or I2C) and if

there is no valid RCW available from one

of those sourced during the boot, it won't

complete the boot process. I recommend that

you verify you are able to set a hard-coded

RCW using your DIP switch. Those hard-coded

RCW options are listed in Table 4-12 in the

reference manual. Make sure that you are able

to set one of those via your DIP switch before you

boot.
