|
This example demonstrates how data can be read and written to/from the |
Flash memory. |
This firmware can be used as default firmware for ZTEX USB-FPGA Modules |
1.15y and 1.15y2. It supports: |
|
During the start-up the firmware (defined in flashdemo.c) reads the |
number of last sector n from sector 0 (dword at position 0) and |
increments it by one. If n is larger than or equal to the total amount |
of sectors, or if it is equal to 0, n is set to 1. |
* Firmware uploading |
* High speed FPGA configuration via USB |
* Configuration data: Storage of device settings in MAC-EEPROM |
|
Then n is written back to sector 0 and sector n is filled with the |
string "Hello World!". |
|
The host software (defined in FlashDemo.java) reads out the string from |
the last sector of the flash memory. |
The upload utility Default.java creates the configuration data structure |
in MAC-EEPROM and can be used to upload the default firmware to EEPROM. |
The wrapper scripts prog-1.15y.sh can be used to do that. |
