Utility that allows dumping the SPI Flash Non-Volatile Memory of the FM10000 family of cards.
|
||||
Utility that allows dumping/flashing the SPI Flash Non-Volatile Memory of the FM10000 family of cards.
|
||||
|
||||
## Requirements
|
||||
* GCC >= 4.4.0 or clang
|
||||
|
|
@ -13,13 +13,18 @@ Utility that allows dumping the SPI Flash Non-Volatile Memory of the FM10000 fam
|
|||
## Compilation
|
||||
* `$ make clean && make`
|
||||
* You can specify whether to use gcc or clang this way: `$ make CC=gcc` / `$ make CC=clang`
|
||||
* An executable named `./fm10k-dump` should now exist.
|
||||
* Two executables named `./fm10k-dump` and `./fm10k-flash` should now exist.
|
||||
|
||||
## Usage example
|
||||
## fm10k-dump usage example
|
||||
* If the chip on the card is known to the tool, it'll set the image size to match. Alternatively it will use the platform minimum of 8Mbit.
|
||||
* `# ./fm10k-dump /dev/uio0 outputImage.bin`
|
||||
* You can also force the image/chip size: `# ./fm10k-dump /dev/uio0 outputImage.bin 32`
|
||||
|
||||
## fm10k-flash usage example
|
||||
* _fm10k-flash_ requires a backup of the existing image before flashing a new one, for safety measures. Use _fm10k-dump_ to take a backup copy of the current state before flashing.
|
||||
* `# ./fm10k-dump /dev/uio0 backupImage.bin`
|
||||
* `# ./fm10k-flash /dev/uio0 inputImage.bin backupImage.bin`
