OTA question about user1.bin and user2.bin

[xinhu.sun]

Hi,

I generated only user1.bin and wrote to flash for user1 or user2 using spi_flash_write and system_upgrade_flag_set function in my firmware upgrade routine, it works fine so far. Is it necessary to generate user2.bin for user2 ?

I compared the contents of user1.bin and user2.bin and found that only the last byte is different.

Regards,
Xinhu

Hi，

Here is the document “99C-ESP8266__OTA_Upagrade” http://bbs.espressif.com/viewtopic.php?f=21&t=413

user1.bin and user2.bin are different，they are the same software but located in different place，please call “make clean” after compiled user1.bin to delete the temporary files of compilation，then compile user2.bin.

Thanks for your interest in ESP8266 !

Hi Faye,

Thanks for the response.

I did make clean before each build. I removed codes which reference the macro __TIME__ and rebuild, the generated user1.bin and user2.bin are exactly same.
I checked the build logs from making user1.bin and user2.bin, the command lines of compile, package and link are same. It means the bin files should be same, am I right?

Hi,

So sorry that I was wrong before..

In compilation STEP 5：
If choosing "5=2048KB(1024+1024)" or “6=4096KB(1024+1024)”，user1.bin and user2.bin would be the same. They have the same flash map..
If choosing other options, user1.bin and user2.bin would be different.

Thanks for your interest in ESP8266 !

Hi Faye,

I tested with SPI_SIZE_MAP=4 (512+512), the bin files are different. The scripts in Makefile can explain that:

Code: Select all

ifneq ($(app),0)
    ifeq ($(size_map), 6)
      LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).2048.ld
    else
      ifeq ($(size_map), 5)
        LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).2048.ld
      else
        ifeq ($(size_map), 4)
          LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).1024.app$(app).ld
        else
          ifeq ($(size_map), 3)
            LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).1024.app$(app).ld
          else
            ifeq ($(size_map), 2)
              LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).1024.app$(app).ld
            else
              ifeq ($(size_map), 0)
                LD_FILE = $(LDDIR)/eagle.app.v6.$(boot).512.app$(app).ld
              endif
            endif
              endif
            endif
          endif
        endif
        BIN_NAME = user$(app).$(flash).$(boot).$(size_map)
endif


Thanks,
