E.setBootCode not working for ESP8266_4MB

[MaBecker]

looks like code cannot be found during dump() and ESP8266.reboot()

maybe this is not working for a Flash map 4MB:1024/1024?

found this: https://github.com/espruino/Espruino/blob/master/src/jswrap_flash.c#L568-L572

@tve do you remember if this value only works for ES8266-01?

[gfwilliams]

have you tried load() as well?

If it's not even attempting to load code, it could be because the 'magic byte' is missing - which could be because the memory area assigned to saving is too large/gets overwritten somehow? you could check with peek32() commands if it exists at the end of the code?

[MaBecker]

looks fine in flash....

What about load()? And is it still in flash after you reboot? Maybe the bootloader messes with it?

[MaBecker]

results for load() ,reboot and flash read, so still in flash after reboots

Wow, strange. I'd have said it might have been jsiInit() getting called with false (as happens normally when BTN1 is pressed at boot) but it's hard-coded to true on ESP8266. Only thing left is to add some prints I think.

[MaBecker]

this output looks strange, side effect console.log is no longer defined....

>this
={
  "console": function () { [native code] },
  "JSON": function () { [native code] },
  "process": function () { [native code] }
 }

You get that if you save code with one version of Espruino and load it with another?

[MaBecker]

Can not reproduce it, so lets forget that!

[MaBecker]

This code for reading boot code will only work if the save area is in the first partition, because only this partition is mapped to memory starting at 0x40200000.

local commit: MaBecker@3145260
EDIT: and MaBecker@641813c

adding -mforce-l32 will dump boot code correct:

>dump()
......
// Code saved with E.setBootCode
console.log('Hi.....');
=undefined
