+Adam Green is working on a new SD card driver for Smoothie.
If that code ends up integrated into Smoothie, possible benefits include insane increases in speed, and being error-tolerant when using an external SD card ( CRC Checks/Error recovery ). Neat !

If you own :

  • A Smoothieboard ( or a compatible board )
  • A SD card that did not came with your board ( those were already tested )
  • A FTDI cable

You can totally help !
We need testing of the code. It’ll help make it better. It’s pretty easy :

  1. Download https://github.com/adamgreen/SDCard/blob/master/bins/SoakTest-Smoothie1.bin
  2. Rename to “firmware.bin”
  3. Paste the file to your SD card
  4. Reset the board. The board flashes the test program
  5. Connect a FTDI cable to the “Serial” ( UART ) port on the Smoothieboard ( near the USB connector ). Note : USB/Serial using Smoothie’s USB port doesn’t work for this.
  6. Connect using your favorite Serial terminal ( I use cutecom ). Baud rate : 9600
  7. Reset the board, follow instructions.

If your run shows any error, or if it ran for a full night without errors, report to Adam.

Adam wrote very nice instructions here : https://github.com/adamgreen/SDCard
If you need help with anything, I’m here.

Cheers, and thanks a lot to all you testers !!!

@Mark_Rehorst Yes, it’ll work fine for some people, but not for others. The point of this project is it’ll work for everybody.

All I ran the test overnight on a SanDisk 4GB Micro HC card with no errors. I will look around for more sd

@Jack_Colletta Please post the output for your test here : https://github.com/adamgreen/SDCard/issues/9
Thanks A LOT for testing !

I just posted it. The only other card I have is an Adata 8GB card and it appears to have been tested.
