On 8/26/10 jorge.castro asked, “As I have post in the past, I’m using the ARM-57TS-LPC3250. By now I’m enabling the bus communications. I2C seems to be done, but trying the SPI I found some issues. Even when in the LTIB configuration I can enable it for the kernel compilation no device node it’s created. Looking about this, someone point me that the board-arm9dimm3250.c file (which is linux/arch/arm/mach-lpc32xx/board-arm9dimm3250.c) doesn’t have necessary SPI support.I’m wondering if you have notice and solve this? I need to implement the SPI communication with some other hardware modules, and we chose this board (SOMDIMM-LPC3250) because, according with the product specifications, there is Linux driver support for this product.”

The ARM-57TS-LPC3250 does not have SPI devices and thus was not a focus for development. SPI was added later by NXP but was not integrated into the FDI version. NXP is working on a patch to solve this.
