SYSTEM FILE LOST

ALIENTEK MINISTM32 24 汉字显示实验，屏幕反复显示 “SYSTEM FILE LOST ” 请问怎么回事啊？谢谢

youngs · 发表于 2013-1-24 19:35:04

补充一下，SD卡实验的时候可以检测到SD卡，但是汉字显示实验时候，屏幕反复显示 “SYSTEM FILE LOST ”，是光盘的带的程序，我直接用出现的状况。谢谢了啊

SD卡需要拷贝一个SYSTEM文件夹进去,该文件在光盘根目录下,有个SD卡根目录文件的文件夹里面.

原子哥，我是按照你说的这样弄的，没读出来字库。但是之前的例程能够读出卡的容量是。你说还是卡的事吗？

现在提示什么?

这个文件夹拷贝到SD卡根目录了么?

里面的内容:

---------------------------------
原子哥，谢谢你了。问题解决了，我下午买张卡，是卡的事。但是有出现的新问题是：每次上电都要更新字库，似乎是字库写到 W25X16 里面后，重新上电，W25X16 里面的字库没了。。我没有修改光盘里面的程序，不知道是什么原因？

是不是你插着JTAG?
或者是不是你的PA0跳线帽跳到1820上了.

回复【9楼】正点原子:
---------------------------------
原子哥，不是以上两种情况，还有别的原因导致掉电 W25X16 内的字库丢失吗？前提我没有更改光盘带的程序。谢谢你了

那不应噶哦
只可能你外部接了什么东西.

---------------------------------
原子哥，问题解决了，是之前我做实验室时候把PA7和PA8用跳线帽给连接到一起了。。。
谢谢你啊！！！非常感谢！

Thanks a lot for your great help.

dariush · 发表于 2014-1-19 15:38:49

I copied the "5，SD卡根目录文件" content to my SDCard root but it still says "system file lost!"!
Any suggestion?
I'm using the "integrated test".

---------------------------------
You should copy files in “5，SD卡根目录文件”，not ”5，SD卡根目录文件“ this folder itself。

正点原子 · 发表于 2014-1-19 17:18:20

Please refer my reply at six floor。

dariush · 发表于 2014-1-19 18:16:46

I copied following three folders:
1-测试用文件
2-system
3-picture
which are inside "5，SD卡根目录文件"
to:
root of SDCard.
still "system file lost" error!

ok，its looks like you meet some serious problem。
please follow these steps：
1，make sure your NRF24L01 Module off the board，do not insert it。
2，found your board’s virtual COM，then open "SSCOM 3.3.exe"，choose the virtual COM port，then set boundrate to 115200. and select “发送新行” chekbox。
3，then send：SPI_Flash_Erase_Chip() ， and wait about 30s later you will receive“;” Its means the total SPI FLASH is erased 。
4，press reset button，restart the system，you will see update files automatically。
5，wait until load main UI。

dariush · 发表于 2014-1-19 22:16:57

Thanks a lot for your reply.
where can i find "SSCOM 3.3.exe"?
The problem is that our boards are different.
I should find the sdcard files for ministm32.
below you can see my board?

dariush · 发表于 2014-1-19 22:40:53

I found the files for my board and the problem solved.it loads the system.
I don't know why i can't choose any of 9 icons?the touch doesn't work.

your board is our MiniSTM32 board。
so the way i saied before was not suitable。It’s for WarShip STM32 board。
for you new problem，i suggest you readjust your touchscreen。
here is the way：
1，Press KEY0 button（Be careful：do not release it！）
2,

ress RST button,and release it(Keep KEY0 pressed),then you will see TP adjust UI.
3, Adjust it.

dariush · 发表于 2014-1-20 01:13:19

I really appreciate your great helps.
Just one question left:
The lcd won't work if the JTAG cable connect to board and i have to disconnect and reconnect it each time.

The BOOT0 jumber also must be changed to (B0, V3.3) for programming.

Is there something wrong with my Jlink programmer or there is a solution for that?

回复【26楼】dariush:
---------------------------------
Keep JTAG connect to board，use SW mode，and reload your code（lcd is used），then your problem maybe solved。
In some examples of our board both SW&JTAG are disabled，such as example 3（按键实验）。
Those examples you will not able to use JTAG for debug or download 。
The solution is connect B0 to 3.3V，and you can download your code，then change B0 to GND，reset the board，your code should work good 。
