麻煩參考design guide document.
debugUSB_log_ok_1816.txt (179.6 KB)
debugUSB_log_04101515.txt (46.6 KB)
附件有两份log:
debugUSB_log_ok-刷了很多次,有一次能够正常完成刷机,硬件不断电的情况下,刷完能够正常进入系统;
debugUSB_log_04101515-是刷完硬件断电重启,进不了系统;
麻烦您帮我看下,看看能不能看出是什么引起的。
你們要不要把所有error 跟對應的log 全部都列出來一下?
聽起來error行為一直都處於不一致的狀況. 一下子可以燒 一下子不能燒 一下子不能進RCM.
從我這邊能看到的log看下來 , 你們一直碰上cvm eeprom讀不到的問題.
E> eeprom: Can't get handle to eeprom device @160
E> NV3P_SERVER: Failed to get eeprom handle for cvm from eeprom manager.
E> NV3P_SERVER: Could not read eeprom for module cvm.
读不到cvm可能有哪些情况引起的?
請問你有xavier nx p3509 devkit可以驗證一下這塊module在那能不能燒嗎
debugUSB_log_04101515是正常的开机log,并没有进入刷机模式
这块模组我们放到正常的载板里面,是可以正常启动的
"正常的載板"是什麼意思… NV devkit嗎?
可以麻煩用精確一點的用詞嗎 這樣可以省下很多來回溝通的過程…
我们有三块自己研发的载板,有一块能正常使用,其他两块异常
那請問那塊正常載板能正常燒錄嗎?
可以的
如果都是用同樣的command進行燒錄的話, 我只能請我們的硬體人員等等來給您建議了
看起來不像軟體這邊的問題
好吧,麻烦您了
Have you compared your failure board to good board? Have you found out the design difference b/w them? It looks like board issue since no problem with good board. Please do that check first.
1、我们好的板子,也有小概率上电异常的情况,跟其他两块板一样,但大部分上电都是正常的
2、板子我们也对比了,没找到问题;
3、其他两块异常的板子,也出现过1次上电正常的情况,感觉可能是上电某个状态异常,引起的问题。
4、刷机模式下主机都能识别到设备。但两块异常的板子都是报cvm异常,这块属于模组设备,cvm异常有可能有哪些问题引起的?
It does not look like module issue as module can work well with other boards. Please check your failure boards to see if any soldering or component issue. Also you should compare your design to reference carrier board design. By the way, which board schematic file did you follow, P3509 or P3768? Below are schematic of P3768, please refer to that to compare.
