i was trying the arm cross development tools for the SAM7P64. it works fine. but when i change it to SAM7-Pxxx, there is an error with the wait status in at91sam7.c.
did anyone know what to change from SAM7P64 to SAM7-Pxxx?
This s really not a OpenOCD question, it belongs in either the “Everything ARM and LPC” or perhaps better in the “Projects” thread.
Anyhow, the ER900TRS uses standard asynchonous serial and should be connected to UART RX and TX and then any two free GPIO pins for the BSY and RDY signals.
