How to execute large application bin files #18

Closed chennakeshavaSoC closed 7 years ago

chennakeshavaSoC commented 8 years ago

Hi, I am using ESP-12F it has 4MBytes SPI FLASH, looking for firmware upgrade OTA. I found your boot loader is capable of handling the images whose size is upto 512kBytes. I have a problem, I want to execute even large images on ESP. My application bin size (user1.4096.new.6.bin is 512kBytes, eagle.irom0text.bin is 260KBytes) is larger than the OTA enabled bin (64KB /180KB) size. So my application is not running.

How can I change the application and library bin size limitations? Is it possible to update the boot loader so that I can change the mapping?

Please suggest me how to proceed further.

Sorry about the slow reply, I didn't get an email notification about this. rBoot can handle images up to 1mb in size, so you shouldn't have a problem.
