fwupgrade application

[lynn.zhang]

Hi

I read UG983 for firmware upgrade, and notice that petalinux 2018.2, there is no fwupgrade application anymore,

from "petalinux -c rootfs", anybody knows where I can find it? And UG983 is kind of old, lastest version is 2014.

Anybody knows latest version?

Thanks

Hi, Sriraksha @lynn.zhang 

fwupgrade is not shipped by Xilinx. It is just a utility from older rootfs used in petalinux.

It is recommended to use other utilities like (swupdate, Mender or RAUC.) in the latest projects. (extracted info from https://github.com/tpetazzoni/fwupgrade)

For example, yocto provides SWupdate as meta layer and you may try adding it to petalinux and see if that works. This post might help you in adding this layer

Hi @sriraksha.nayak ,

What is you actual requirement here, Are you looking for OTA(Over-the-air) update from older version to newer version or Just upgrading the images from incremental builds?

hi @sandeepg 

I would like to know how to flash the firmware when its Running bare-metal/FreeRTOS.

 About firmware update i mean to say adding BOOT.bin in flash (board doesnt have any firmware at present its a dead board). 

SDCARD option is ruled out.So if updating BOOT.bin over usb is available or Jatg or if any other options?

Regards,
Sriraksha

Hi @sriraksha.nayak ,

If you have SD card on your hardware then you can use SD card to load flash the BOOT.bin to QSPI parition.

If you don't have SD card then only way to program the BOOT.bin to flash on new board using JTAG boot mode via XSDK(2019.1 and below release) or Vitis(2019.2 and above release) tool(Flash Programming method).

For more details refer UG1209.

Hi @sandeepg,

Thank you for the reply.

So you are saying other than sd card and jtag we dont have any other options to to push bins in dead board? over usb is there a provision?

we were checking if over usb if its possible?

Hi @sriraksha.nayak ,

If you have USB boot mode options on your board.

1. Create a BOOT.bin with DFU enabled
2. Boot from DFU so that BOOT.bin is copied to OCM and FSBL and u-boot should comes up
3. Halt at u-boot
4. Copy the QSPI BOOT.bin to DDR address
5. Use sf probe, erase and write commands to program BOOT.bin to flash as show below.

In below example I used fatload mmc(using SD) you can replace with tftp or dfu commands to copy the BOOT.bin to DDR address.

Hi @sandeepg,

We were looking for usb options for booting but looks like its not available.

We can find the current boot mode MIO strapping pins in the Zynq 7000 TRM(ug585-Zynq-7000) page 166.

Suggest us the best option to push production code into the flash.

check attachment for reference.

Sriraksha

Hi @sriraksha.nayak ,

Sorry my bad I thought its ZynqMP architecture, Yes for Zynq7000 we don't have USB boot mode.

Hence you need to use JTAG boot mode.
