Did you compile it as a 32Mbit Flash ? Choose 4 or 6 in Step 5 of compilation, with boot.

Did you choose Flash size 32Mbit when downloading bin files into Flash by Espressif Flash download tool ?

If your problem is still unsolved, please provide the captured picture of your Espressif Flash download tool while downloading.

flash vendor: E0h : N/A flash devID: 4016h QUAD;32Mbit crystal: 26 Mhz

my bin file's size is 174 KB (177.653 Bytes).
i burn my bin file @ 0x81000. when i read 3000 byte from it using spi_flash_read((uint32)0x81000, (uint32 *)something, 3000);
it failed miserably.

*sigh* *T_T* /swt :shock:

i've already try to burn it @ 0x10000, and i can read it successfully using spi_flash_read((uint32)0x10000, (uint32 *)something, 3000);

which one is the bugger here ? the "flash download tool v1.2" or the "spi_flash_read function" ???

anyone ever experienced this ? please advice

thanks in advance. if this is a bug, no need to pay me the bounty. i just want it solved, nothing more, nothing less.
