I've lately been doing the data transfer stuff using STM32F407 development boards. Cheap ($12 shipped), with a 168MHz ARM CPU and 84Mhz peripheral clocks with multichannel DMA to 192K RAM. Lots of fast 5V tolerant GPIO.
$12 development boards? Which ones do you use?
In my case, I use the SDIO facility (4 wire) to an SDHC, with Chan's FATFS filesystem code. Do all your imaging to SDHC (a 16 or 32GB card should image a lot of RL02s) and then read the card on a PC platform. Simple, fast and cheap. If you need UARTs, they're on the chip as well and can run stupid-fast.
Do you use gcc, or the eval tools from STM? Thanks, emanuel
