1MB FLASH rboot problem
I am trying to modyfy Basic_rBoot sample to work with ESP8266-01 with 8Mb FLASH (2 x 512kB) - RBOOT_BIG_FLASH ?= 0 and RBOOT_TWO_ROMS ?= 1
I think with sming version changes the rom0.ld was moved to sming/compiler/ld, renamed and reduced in size. So simple Copy rom0.ld to rom1.ld from readme.txt doesn't work.
In my oppinion there should be Makefile-rboot.mk modified RBOOT_LD_1 ?= rboot.rom1.ld.
I am not sure if copy rboot.rom0.ld to rboot.rom1.ld which is much smaler than old rom0.ld file.
Finally question from beginer - how should I modyfy rboot.rom0.ld nad rboot.rom1.ld to work.
Are you able to prepare working example of Basic_rBoot for ESP8266-01

I faced out the same Issue. I've a ESP8285 with integrated 1MB Flash. At first i struggled over it by using OTA.
If I flash the same ROM to slot 0 and 1 I can boot from both. If I flash a different ROM to slot 1 I cannot boot from slot 1, it will fail. Sometimes it hangs or it will show exceptions.
I think there is a mapping problem. If I boot from slot 1 and try to update slot 0 with OTA the system will crash after erase of the sector 2.
Ok, I've found the issue. I copied rboot.rom0.ld to rboot.rom1.ld and modified the Makefile-rboot.mk. I modified irom0_0_seg of the rom1 file to org = 0x40282010, len = (1M - 0x2010).
I'm not firm with ld files, maybe there could be an option to modify the linker file automatically or dynamic create the file.
ok, Update on this. It is enough to copy the rboot.rom0.ld as rom1.ld to your project root and modify the irom0_0_seg depending on your flash size: (https://github.com/raburton/rboot#linking-user-code)
