@deffn {Flash Driver} w600
|
||||
W60x series Wi-Fi SoC from WinnerMicro
|
||||
are designed with ARM Cortex-M3 and have 1M Byte QFLASH inside.
|
||||
The @var{w600} driver uses the @var{target} parameter to select the
|
||||
correct bank config.
|
||||
|
||||
@example
|
||||
flash bank $_FLASHNAME w600 0x08000000 0 0 0 $_TARGETNAMEs
|
||||
@end example
|
||||
@end deffn
|
||||
|
||||
@deffn {Flash Driver} xmc1xxx
|
||||
All members of the XMC1xxx microcontroller family from Infineon.
|
||||
This driver does not require the chip and bus width to be specified.
