Just been looking at the flashless LPC range for a couple of projects & wondered why NXP didn't put an option in the bootloader to boot from an external SPI flash device and/or I2C EEPROM into SRAM- there would be plenty of code space to do it as the internal flash stuff wouldn't be needed, and could be a useful addition for apps that don't need a large program memory. SPI flash chips are...

Hi lpc2000 group! For a data logger I want to store incoming data on a SD-flash memory card as quickly as possible. I am using LPC2103 runnung at 4x16MHz, and I have connected a 1GByte SD-Flash to the SSP (SPI1) port; no FAT- filesystem (for speed reasons), just pure "data dump" onto the flash. I have never used SPI nor SD Flash cards before, so this might be impossible or stupid, but...
