MEMX
|
|
||||||
^^^^
|
|
||||||
|
|
||||||
If you use the GCC AVR toolchain from the Atmel Studio, then you can
|
|
||||||
enable suppport for the MEMX storage:
|
|
||||||
|
|
||||||
CONFIG_AVR_HAS_MEMX_PTR=y
|
|
||||||
|
|
||||||
If this support is enabled, then all strings will be saved in FLASH and
|
|
||||||
standard string-oriented interfaces such printf() will change so that
|
|
||||||
they accept memx pointers.
|
|
||||||
|
|
||||||
This means that (1) ALL strings must lie in FLASH, and (2) since the
|
|
||||||
strings are moved from SRAM to FLASH, you will save a LOT of SRAM usage
|
|
||||||
in some configurations that use a lot of string memory (such as the
|
|
||||||
ostest and nsh configurations).

MEMX
|
|
||||||
^^^^
|
|
||||||
|
|
||||||
If you use the GCC AVR toolchain from the Atmel Studio, then you can
|
|
||||||
enable suppport for the MEMX storage:
|
|
||||||
|
|
||||||
CONFIG_AVR_HAS_MEMX_PTR=y
|
|
||||||
|
|
||||||
If this support is enabled, then all strings will be saved in FLASH and
|
|
||||||
standard string-oriented interfaces such printf() will change so that
|
|
||||||
they accept memx pointers.
|
|
||||||
|
|
||||||
This means that (1) ALL strings must lie in FLASH, and (2) since the
|
|
||||||
strings are moved from SRAM to FLASH, you will save a LOT of SRAM usage
|
|
||||||
in some configurations that use a lot of string memory (such as the
|
|
||||||
ostest and nsh configurations).
|
|
||||||
|
|
||||||
UPDATE 2016-01-07: Unfortunately, there is an issue. When I enable
|
|
||||||
CONFIG_AVR_HAS_MEMX_PTR=y in the nsh/ configuration, I get a number
|
|
||||||
of link time errors of this form:
|
|
||||||
|
|
||||||
FILENAME.c:(.text+0xOFFSET): warning: internal error: out of range error
|
|
||||||
|
|
||||||
This same build configuration works for the arduino-mega2560 so I am
|
|
||||||
suspecting some issue with the toolchain support for the AT90USB (avr:5)
|
|
||||||
vs the Atmega2560 (avr:6).
