booting from Quad Spi after hard reset

[bdina77]

Hello,

I'm having an issue with my arty board, after following the tutorial on store my program from SDK, the system works after pressing the reset button on the board but when I power cycle the board my program doesn't run.  Do I need to flush the memory after each iteration of flashing the device or is there something I am missing?

I figured it out, I had the jumper J1 on when i was programming the arty so it loaded my bootloader into my nvram instead of my bram.

works fine

Hi @bdina77,

Glad to hear you figured out the issue. Than you for sharing what it was.

Update,

it only works for a simple hello world program nothing more complicated.

Hi @bdina77,

Are you using the How To Store Your SDK Project in SPI Flash tutorial? Are you able to share you project and a screen shot of the block design.

thank you,

Jon

Here is the block design, Yes that is what ive been using

Just to add I am using 2016.4 on both my Windows 10 machine and CentOS 7 machine. 

 

I had a question about the difference between mig_7series_0_memaddr and what you guys have in your SDK FLASH tutorial which is: mig_7_series_0

I am using the board.prj configuration file for my project should I make a constraint file with the pin outs listed on the Reference manual?

 

EDIT:

Did some more testing with the bootloader when powercycled it gets hung up at the beginning of the line:

So I figured it that when I put a delay in very beginning of my SREC SPI BOOTLOADER program that I am able to get the system up and running after a power cycle.  The lower limit is 3 sec, or what the sleep() dictates its 3 seconds, when its removed or I drop below 3 sec the system gets stuck.  Is this normal? I know of putting delays for big applications to get everything in sync but I haven't seen anything online about this. 

 

Thanks for all your help @jpeyron

Hi @bdina77,

Glad to hear you are able to get your design working. I have not heard of this being an issue. I would guess that this is due to the power up of the different rails and IC's.

cheers,

Jon
