Hello,
Iam using the SB70lc card;however, after reading the "EFFS-ProgrammersGuide" I couldn't find the pinout to connect an external flash card to the sb70lc card.
On page 6 of that manual the signal and the eschematics refer to modxxxx.. there is no JP15 header in the sb70lc board.
Has anybody used the external Flash with the sb70lc board?
Thanks
Aldus
External SD card interface
Re: External SD card interface
Do you have the schematic for the SB70LC development board that came with your kit? It has the SD card interface on it.
Re: External SD card interface
The schematic for the SB70LC carrier is here:
C:\nburn\docs\platform\schematics\SB70LC-ADPT-100CR-SCH-R1p3.pdf
The SPI_DOUT, SPI_CLK and SPI_IN pins must be connected as shown. The CS, CD and WP pins are used in GPIO mode. This means you can swap these with any GPIO configurable pin if you want to use those default pins for some other function. You will then need to modify the related functions in the mmc driver ( spi_cs_hi, spi_cs_lo, get_wp, get_cd ) :
C:\nburn\SB70LC\system\mmc_mcf.cpp

Re: External SD card interface
thanks Larry.
In the schematics folder of my dsitribution I found the SB70LC-ADPT-100CR-SCH-R1p2.pdf file. Which are the differences between the schematic R1p2 and R1p3?
