openipc / uget

Simple but compact wget replacement for embedded devices

μget

Simple utility to help CI guys do their job in constrained environments to download and run binaries in /tmp. Size of μget is around 4Kb.

Features

• Could be used as curl or wget replacement. In my case it's convenient to PUT binary to S3 bucket and then run it on device

• Supports only HTTP (we need deal with size), no redirects yet

• No fancy error messages inside binary, returns only exit codes from defined preset (see Error codes section).

Usage

• As curl replacement: uget ifconfig.me

• Ad-hoc utility to download and run binary:

$ ./uget run openipc.s3-eu-west-1.amazonaws.com/ipc_chip_info

Transferring to device using telnet

# on your Linux workstation
$ ./bin2sh uget > uget.sh
# login via telnet to embedded device, copy-paste text from uget.sh
# target binary will reside in /tmp
$ ./uget example.com

# if target system doesn't support printf use
$ ./bin2sh -echo uget > uget.sh

Demo

Error codes

Error code	Description
0	everything is ok
1	general error code
2	socket creation error
3	DNS resolution error
4	connection error
5	send error
6	incorrect command line options

• HTTP response codes other than 2XX are transformed from XYZ number to XZ exit code (so 44 means 404, or 52 means 502)

uget's Issues

Provide 'release' binary to avoid needing users to install the hisilicon SDK

As per title.

Provide a release with ready to go binaries to avoid users needing to install the cross compiler toolchain and SDK
