... tricking the ESP when it tries to access flash, but it's actually tries accessing the RAM chip, which has the running app. So basically what you would do is, boot from Flash, write SD card binary data into the RAM, modify the flash partition table, and reboot. Here the RAM voltage should be pro...

I would like to use PSRAM because it is more suitable for constant rewriting. It would be possible to use Flash, but i would really like to avoid it. I want to go that one extra...

Is it possible to use PSRAM instead of flash chip? I mean executing code from PSRAM mapped on 0x400C2000 area. From datasheets, it seems that read instruction codes are matching. Of course there has to be a way to load code into PSRAM. This leads to my second question. Is it possible to boot code fr...
