在SPC570S-DISP上使用SD2进行串行读/写却出错了是怎么回事？

你好工作，
首先，您是否使用Pinmap Editor启用了LINFLEX1 Pins？
您应该使用PLS进入CPU Windows并在汇编程序模式下检查LR以检查生成断言的位置。

Hello Job ,
First , Did you enable LINFLEX1 Pins with the Pinmap Editor ?
You should go in CPU Windows with PLS and check the LR in assembler mode to check where the assert is generated.

嗨二湾，
我没有使用PinMap编辑器启用LINFLEX1，感谢您指出。现在我启用了它，程序可以运行，但是当我写入SD2时，我仍然无法在LINFLEX1 TX引脚上接收数据。
根据UM2025用户手册，LINFLEX1-TX映射到PD [8]，但是当我使用PinMap编辑器时，它映射到PA [8]，参见鼠标提示文字的附加屏幕截图，我能够去到I / O设置并将MSCR索引从8更改为56以使其映射到PD [8]。我使用了相同的LINFLEX0高级设置，但仍然无法从B21或C19接收数据。
我做错了什么或忽略了什么？
最好的祝福，
工作

Hi Erwan,
I didn't enable the LINFLEX1 with PinMap editor, thank you for pointing out that. Now that i have enabled it, the program can run, but i still not able to receive data on the LINFLEX1 TX pins when i wrote to SD2.
According to the UM2025 User Manual, the LINFLEX1-TX is mapped to PD[8], however when i use the PinMap editor, it mapped to PA[8], see attached screen shot of the mouse tip text, I was able to go to I/O settings and change the MSCR Index from 8 to 56 to make it map to PD[8]. I used same advance setting of LINFLEX0, but still not able to receive data from B21 or C19.
Anything i did wrong or overlooked?
Best Regards,

你好工作，
您是否尝试在RPI3或PC上读/写SD2？
如果RPI3，如果直接由GPIO，你需要一个模块
我们已经使用过LINFLEX0（串行PC）和LINFLEX1（串行=＆gt; BT设备）
它运作良好。

Hello Job ,
Did you try to read/write SD2 on RPI3 or PC ?
if RPI3, if directly by GPIO, you need a module

We have already used LINFLEX0 (Serial PC) and LINFLEX1 (Serial => BT Device)
it works well.

嗨二湾，
我通过连接GPIO引脚从RP3读取SD1和SD2，我终于在不使用RS232到TTL转换器模块的情况下工作了。我发现从SD2读取与从SD1读取没有区别，我不知道为什么需要RS232到TTL转换器。
首先，我使用pinmap编辑器获取PIN名称，MSCR索引和功能索引，然后我转到I / O设置下的Board Initialization Component RLA，使用PIN名称，MSCR索引和功能索引（SSS）添加条目，我有不知道MSCR和SSS是什么，所以我花了一些时间将它们与值pinmap编辑器属性相提并论。 （我必须承认这并不容易）。我测试了LINFLEX1 TX的PIN 6和PIN 48，两者都有效，PIN 6属于PA [8]，PIN48属于PD [8]。
SPC570S-DISP板有4 x 37 I / O引脚阵列，使用UM2025硬件概述，我试图为我的TX找到PD [8]的相应引脚，
我发现B21连接到PD [8]，C19也连接到PD [8]。我连接到B21，我能够接收数据，但C19没有数据。当我试图访问LINFLEX0时，我发现A10没有数据，C11有数据，尽管两者都连接到PA [13]。
从UM2025硬件概述，第18/24页和第19/24页看下表，B21和C19是否都连接到PD [8]并应提供数据？
最好的祝福，
工作

Hi Erwan,
I read SD1 and SD2 from RP3 by connecting the GPIO pins, i finally made it work without using the RS232 to TTL converter module. I found read from SD2 is no difference compare to read from SD1, i don't know why a RS232 to TTL converter is needed.
First i used pinmap editor to get the PIN name, MSCR index and function index, then i go to Board Initialization Component RLA under I/O Settings to add the entry using the PIN name, MSCR index and function index (SSS), i had no idea what MSCR and SSS is, so it took me awhile to assosicate them to the values pinmap editor properties. (i must admit it wasn't easy). I tested PIN 6 and PIN 48 for LINFLEX1 TX and both works, PIN 6 belongs to PA[8] and PIN48 belongs to PD[8].
The SPC570S-DISP board has 4 x 37 I/O pin array, using the UM2025 Hardware overview, i tried to find the corresponding pin for PD[8] for my TX,
i found B21 is connected to PD[8] and C19 also connected to PD[8]. I connected to B21 and i was able to received data, but C19 has no data. When i was trying to access LINFLEX0, i found A10 had no data and C11 has data despite both connected to PA[13].
Look at below table from UM2025 Hardware overview, Page 18/24 and Page 19/24, does B21 and C19 both connected to PD[8] and should provide data?
Best Regards,
Job
