Hi, i am working on a project using the lpc1768 on the landtiger board to accesss some files from the sd card(16GB space-32bit pcm format), the issue i have is that even after powering the sd(LD3 is on) and after calling the sd_init() function from the sdcard.c file the sd card stays undetected. It is also important to note that the example from cortex3 of sd card read and write provides the same result (sd card power on but not detected).
Please no links to obvious things like the manual or the datasheet or examples.
Thank you for your help. Kind regards. Ryuzaki
Obviously do some deeper/better debugging.. Keil is not the vendor of this board, unlikely to be people with specific experience with it here.
Determine if the card detect GPIO indicates the presence of the card, or not. Dig into the SPI interactions with the card. Any of that working? Responds to any commands? Code supports SDHC/SDXC type cards? Does a 2GB card work?

Thanks i will continue searching.
