可以使用printf命令来控制输出格式，将addr以16进制的形式输出。修改代码如下：

start_addr=0x30000000
end_addr=0x30000003
data_write=0x55AA55AA
count=0
match_count=0

# 写入数据
for ((addr=$start_addr; addr<$end_addr+1; addr=addr+1)); do
    printf "addr: 0x%x\n" $addr
    echo -ne "\x55\xAA\x55\xAA" | dd of=/dev/mem bs=4 count=1 seek=$(($addr/8)) conv=notrunc 2>/dev/null
    data=$(echo -ne "\x55\xAA\x55\xAA" | hexdump -e '/4 "%08x\n"')
    data_text=$(echo -ne "\x55\xAA\x55\xAA" | hexdump -e '/4 "%08x\n"' | sed 's/../& /g')
    echo "data_text: $data_text"
    #echo "data: $data"

    data_read=$(dd if=/dev/mem bs=4 count=1 skip=$(($addr/4)) 2>/dev/null | hexdump -e '/4 "%08x\n"')
    data_read_text=$(dd if=/dev/mem bs=4 count=1 skip=$(($addr/4)) 2>/dev/null | hexdump -e '/4 "%08x\n"' | sed 's/../& /g')
    echo "data_read_text: $data_read_text"
    #echo "data_read: $data_read"

    if [ "$data_read" == "$data" ]; then
        match_count=$((match_count+1))
        echo "match_count: $match_count"
    fi
    count=$((count+1))
    echo "count: $count"
done

# 输出结果

# 判断结果
if [ $match_count -eq $count ]; then
    echo "PASS"
else
    echo "FAIL"
fi

这样输出的addr就会以16进制的形式显示。
