Hello Chuck,
I started with the stm32f407 a while ago, but gave up,
the support wasn't there than.
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
