Angus Gratton	bfd38cd1e2	Experimental support for storing const strings in SPI flash or IRAM ... As discussed in #11 Known limitations: - Only supports l8ui/l16ui - Unoptimised load routine - Not called from DoubleExceptionHandler but should be - Doesn't restore state properly when falling through to fatal exception handler	2015-08-10 12:03:03 +10:00
Angus Gratton	d685581829	Syscall hander: Fix a3 save address ... (SDK doesn't use syscall exception so bug probably never hit?)	2015-08-10 11:54:30 +10:00
Angus Gratton	bed6907d22	Exception vector address must be 256 byte aligned ... Not actually a problem with the current linker script as the address is predetermined there at start of IRAM, but might as well be accurate about it. As per advice from @foogod on esp8266-re mailing list: https://groups.google.com/d/msg/esp8266-re/1ljIY3Zttbo/HvzHSWOLCgAJ	2015-08-06 09:54:46 +10:00
