SDS1102CML+ and using TFTP to flash firmware

[smittyinthesky]

Still having issues with a missing /dev/ttyO0 when I boot my 'scope, but wanted to share this bit of info.

Using the files provided by tautech in this thread https://www.eevblog.com/forum/testgear/siglent-sds1102cml-non-responsive-any-ideas/msg3554063/#msg3554063, I populated a directory C:\tftp on my desktop and unzipped those files into it. (I seem to be missing a rootfs.img?)

Then, using the interrupted U-Boot session, I updated the 'scope's networking settings using the following commands:

editenv gatewayip
editenv ipaddr
editenv serverip

by default these settings are:

gatewayip=10.11.13.1
ipaddr=10.11.13.250
serverip=10.11.13.19

I downloaded tftp64 to use as my TFTP server. Using most of the defaults works, just need to point it to your files at C:\tftp.

If we examine printenv, we can see some command syntaxes pre-populated.

Code: [Select]

a=echo tftp download MLO,u-boot.img,uImage,ubi.img image fpga nand ...; run m; run u; run k; run f; run b; run r; run d

This command "a" downloads via TFTP the files named:

MLO
u-boot.img
uImage
rootfs.img
logo.bmp
firmdata0.img
datafs.img

You can then kick off a TFTP based update of your device like this:
