Note:
U1A is divided in two parts. This is done by the jumper JP1. In the upper part, the first
sector (sector 24) at address 0x01100000 must be programmed with a boot sequence
to be debugged. This sector can be mapped at address 0x01000000 (or 0x0 after a
reset) when the jumper JP1 is in the USER position. See “Appendix A – Configuration
Straps” on page 5-1.
The Flash Uploader included in the EB40A Boot software is the same Flash Uploader
factory-programmed in the Flash-based AT91 devices, the AT91FR4042 and the
AT91FR40162/S. The Flash Uploader allows programming to the Sector 24of Flash
through a serial port. Either of the on-chip USARTs can be used by the Flash Uploader.
To boot from the application downloaded in the Sector 24, the downloading address
must be 0x01100000. Other sectors in plane B can be used to store constant data. The
boot starts the Flash Uploader if the SW3 button is pressed at reset.
The procedure is as follows:
1. Connect the Serial A (or B
