go-rkvendorstorage

A pure Golang implementation of Rockchip rknand vendor storage interface.

Usage

package main

import (
	"fmt"
	"github.com/jamesits/go-rkvendorstorage"
)

func main() {
	size, data, err := rkvendorstorage.Read(rkvendorstorage.IDVendorSN)
	fmt.Printf("size=%d, data=%s, err=%s\n", size, string(data), err)
}

See read_test.go for more examples.

Caveats

• Linux is the only OS supported for now
• An artificial 1024-byte limit is applied to the read/write buffer
• Endianness is hardcoded as little endian

If you have valid use cases that exceed the current limitations, please raise an issue.
