Hello everybody, I've been working for a long time with the RCM3700 in a somewhat complex application. Now I'm thinking on moving to the RCM6700, because I'm getting short of memory and processing capabilites. The application uses the RCM3700's serial flash for configuration storage and data logging. I don't use any filesystem for that because I do flash r/w operations by hand. In RCM3700...

Currently, I connected my RCM3700 to a fingerprint sensor via serial connection. The RCM3700 will basically send commands over to the sensor and the sensor will reply. However, when i tried to send a command over to the sensor to get a image of around 8k bytes, the serial output over at RCM3700 is able to show only close to 1k bytes (observed via printf). Is it because that the bu...
