【問題】mzk-w04nu? ttl?

[pc054999]

我當初就是用Wireshark的Fliter來看udp.port == 4919
現在Wireshark一直出現who has 192.168.1.1 tell 192.168.1.2
完全ping不到192.168.1.1了
進不去failsafe mode

該去拜拜了....
應該要刷回原廠再更改的
像這種刷好,系統reboot後,出現錯誤常見嗎?
沒有道理出現這樣吧?
因為我之前在這台刷過名字一樣版本不一樣的sysupgrade
那時候很順利的刷完

這次真的樂極生悲,我還很開心的去喝東西想說終於好了
回來只看到error error........

PuTTY我上面有提到兩邊的設定是一樣的


傳輸線我是直接買改好的成品,所以應該是正確的,我會mail給賣家,再問清楚
這邊測試
他標在網頁上的tx線,確實電壓變動得很頻繁
可是我的電表蠻簡陋的
tx要轉到2000m才測的到(變動頻繁),rx轉2000m會爆表,要轉到20(久久變動)
兩邊的基準根本不一樣...

謝謝啦
回答我這麼多問題

[FYI]

傳輸線應該是正常的, 但小弟的意思是TX/RX 是否弄反了? 否則開機至少會看到亂碼, 而不是什麼都沒有

數位電錶打到DC V 檔或類比電錶打到DC 10V 檔, 再測試傳輸線TX 對GND, 然後從PuTTY 按任何按鍵, 應該也要看到從0-3.3V 之間變動

哪兒買的傳輸線啊?

[pc054999]

我有試著tx/rx反接一樣接不到訊號

我這台電表只有DC 2000mv 20v
我轉20v 測試那兩條

他的range必須是0-3v 這麼寬?
我這邊測並沒有那麼寬
你這麼一說 我回去量機器(mzk-w04nu)的TX
真的是0-3v 跳動

我這條TX(DC in)棕色電壓是0.03v-0.04v上下跳動
而RX橘色是維持3.43-3.44v 久久跳動
跳動頻率是tx比較大

線有問題?
是不是TX(DC in) 該3v?
然後他range應該要0 - 3v

在這買的
USB 轉 TTL 4線杜邦頭(3V5V外部設定) ( UART RS 232 ) 成品 線長約120cm

[FYI]

作者: pc054999

我這條TX(DC in)棕色電壓是0.03v-0.04v上下跳動
而RX橘色是維持3.43-3.44v 久久跳動
跳動頻率是tx比較大

線有問題?
是不是TX(DC in) 該3v?
然後他range應該要0 - 3v

賣家PCB 顯示:

紅線 3.3V
橙線 RX
棕線 TX
黑線 GND

賣家成品卻顯示:

紅線 VDD (5V in)
橙線 RX
棕線 TX (DC in)
黑線 GND

請問紅線的電壓是多少?

商品標題顯示 "3V5V外部設定", 到底 "5V in" 和 "DC in" 是何用意? 小弟參考其他類似商品, 紅線 3.3V 可能是用於輸出, 你不妨詢問賣家詳細用法, 但不管如何, TX 電壓不正確, 而RX 怎麼可能會收不到資料?

小弟的TTL RS232 傳輸線TX 正常為3V, RX 為3V, Baud rate 設600bps 比較容易觀察電壓變化, 連續傳送資料時, TX 電壓會下降到1V

另請問你為何沒用sysupgrade 升級而用比較危險的mtd -r write?

[pc054999]

我把紅線 VDD (5V in)和GND互接測不到電壓(0v)

傳輸線用法的部分,店家尚未回覆我...

sysupgrade
mtd -r write
因為我不知道mtd -r write比sysupgrade危險
我之前更新版本都是直接用mtd -r write....
所以這次也是用那個指令

假如對方沒有回應
我在去買條傳輸線來試試看好了

[pc054999]

我買一條新的ca-42,自己動手接上
可以正常接收到訊息
那條傳輸線可能有點問題

我按照Planex (PCI) MZK-W04NU Atheros AP81 platform router with USB敘述重新刷

接上ttl線後
第一次是刷原廠mzkw04nu_v10323.bin
第二次是刷Backfire 10.03.1-rc4 openwrt-ar71xx-mzk-m04nu-squashfs-factory.bin
兩個reset後都是同樣情況
有差別的是tftp上傳的時間
原廠的好像10min左右就傳好了
openwrt的傳了2hr.....

明天我會在傳一次原廠的試驗看看

[pc054999]

原廠的和新版的openwrt都不行

reset後就通過

mzkw04nu_v10323.bin 7680kb

後來我抓舊的的Backfire 10.03 Released
openwrt-ar71xx-mzk-w04nu-squashfs.bin 7616kb
reset後就通過

0x007c0000 - 0x00050000 = 0x770000
7616kb (7798784 bytes) = 0x770000
7680kb (7864320 bytes) = 0x780000

你載入7680KB (trunk 版), 卻只寫入7616KB, 所以檢查碼當然會錯誤!

事實上對你來說, 原始 "config" 已經不存在, 所以空間可以多出0x20000, 也就是檔案長度可達0x790000 (0x50000-0x7e0000), 因此U-Boot 指令應該調整為:

ar7100> erase 0xbf050000 +0x790000
ar7100> setenv serverip 192.168.1.11; setenv ipaddr 192.168.1.1
ar7100> tftp 0xa0800000 openwrt-ar71xx-mzk-w04nu-squashfs.bin
ar7100> cp.b 0xa0800000 0xbf050000 0x770000
ar7100> reset

erase 長度0x790000, 但cp.b 應該以檔案實際長度為主, 10.03~10.03-rc3 檔案長度都是7798784, 只有trunk 才是7864320

此外, MZK-W04NU 的Reset 按鈕似乎只能重置U-Boot 環境變數, 可惜了! 枉費小弟也很欣賞Planex 的用料, 你要是再刷不成功, 其他網友怎麼敢再去敗這台? 你先刷trunk 版, 再試10.03-rc3
