@deffn {Flash Driver} niietcm4
This drivers handles the integrated NOR flash on NIIET Cortex-M4
based controllers. Flash size and sector layout are auto-configured by the driver.
Main flash memory is called "Bootflash" and has main region and info region.
Info region is NOT memory mapped by default,
but it can replace first part of main region if needed.
Full erase, single and block writes are supported for both main and info regions.
There is additional not memory mapped flash called "Userflash", which
also have division into regions: main and info.
Purpose of userflash - to store system and user settings.
Driver has special commands to perform operations with this memmory.
@example
flash bank $_FLASHNAME niietcm4 0 0 0 0 $_TARGETNAME
@end example
Some niietcm4-specific commands are defined:
@deffn Command {niietcm4 uflash_read_byte} bank ('main'|'info') address
Read byte from main or info userflash region.
@end deffn
@deffn Command {niietcm4 uflash_write_byte} bank ('main'|'info') address value
Write byte to main or info userflash region.
@end deffn
@deffn Command {niietcm4 uflash_full_erase} bank
Erase all userflash including info region.
@end deffn
@deffn Command {niietcm4 uflash_erase} bank ('main'|'info') first_sector last_sector
Erase sectors of main or info userflash region, starting at sector first up to and including last.
@end deffn
@deffn Command {niietcm4 uflash_protect_check} bank ('main'|'info')
Check sectors protect.
@end deffn
@deffn Command {niietcm4 uflash_protect} bank ('main'|'info') first_sector last_sector ('on'|'off')
Protect sectors of main or info userflash region, starting at sector first up to and including last.
@end deffn
@deffn Command {niietcm4 bflash_info_remap} bank ('on'|'off')
Enable remapping bootflash info region to 0x00000000 (or 0x40000000 if external memory boot used).
@end deffn
@deffn Command {niietcm4 extmem_cfg} bank ('gpioa'|'gpiob'|'gpioc'|'gpiod'|'gpioe'|'gpiof'|'gpiog'|'gpioh') pin_num ('func1'|'func3')
Configure external memory interface for boot.
@end deffn
@deffn Command {niietcm4 service_mode_erase} bank
Perform emergency erase of all flash (bootflash and userflash).
@end deffn
@deffn Command {niietcm4 driver_info} bank
Show information about flash driver.
@end deffn
@end deffn
@deffn {Flash Driver} nrf51
All members of the nRF51 microcontroller families from Nordic Semiconductor
include internal flash and use ARM Cortex-M0 core.
