Hello. I'am using a this example code (TMS570LC43x_HDK_SDCard_mibspiDMA « Application - hercules_examples/hercules_examples - Software Examples for Hercules Processors) and I'am adapting it for to use with my board. I have a problem when I use a ls, chdir or cat commands. The code come back a FR_NOT_READ when I execute theses commands.
I am not sure where is the problem. I leave my proyect.
Thanks a lot for your help !!!
The SD card example uses MibSPI2, here is the config of MibSPI transfer group:
The TG0 is used to transfer command, and TG1 is to transfer data from the file.
Yes, you can use any of the SPI modules or MibSPI modules.
You can try this example which was developed for RM48x HDK. RM48 and TM570LS31x are pin-2-pin compatible, have the same CPU architecture (cortex-R4F). The difference is that RM48 is a little endian device, but TMS570LS31x is a big endian device. When you compile the project, please select TMS570LS3137, and BE32, and proper RTS for BigEndian parts:
Thanks for your help! Now, when I Debug the project, I have this message:
Could it be that something else needs to be changed? I already made the changes in CCSS General.
Thanks a lot !!
Yes, It is like this.
The strange thing is that the other projects that I have in my CCS are the same, and in all of them I get the same error. Before, they all worked fine. Maybe something has changed about the CCS? Thanks.
sorry, I meant that I don't have this JTAG connector to debug.
I program with the USB cable. I will try to get the JTAG connector if it is essential for this.
Is there any way to erase the flash like this? Thanks !
I got it. You use the built-in xds100v2 emulator through the mini USB connector.
1. In CCS10.x, connect target through XDS100V2
2. Open CCS10.x-->Tools-->On-Chip Flash
3. Under Erase Option, select "entire flash", the click "Erase Flash"
Thank you QJ Wang. I am very close to achieving it ... But you can see that I am missing one last step. Create a target config, debug it, go to Tools -> on-chip, "entire flash" and put "Erase Flash", but the following poster appears:
I don't know if anything can be done ... If I'm not trying to get the JTAG connector. Thanks a lot !
You can use on board xds100v2 emulator, so you don't need a JTAG connector.
Is the xds100v2 connected to the target?
Please refer to this link to learn how to create a custom target configuration:

Hello QJ Wang. Yes, I create my custom card like that link, but unfortunately I can´t solved my problem.
My custom card is:
But I have the same message when I erase the flash:
