The problem is in the memory chip, Puya P25Q80H
The software need a patch as described in: https://github.com/esp8266/Arduino/issues/4061

I change the file ESP.cpp, replacing the function EspClass::flashWrite with:

Code: Select allbool EspClass::flashWrite(uint32_t offset, uint32_t *data, size_t size) {
   static uint32_t flash_chip_id = 0;

   if (flash_chip_id == 0)
      flash_chip_id = getFlashChipId();
   ets_isr_mask(FLASH_INT_MASK);
   int rc;
   uint32_t* ptr = data;
   if ((flash_chip_id & 0x000000ff) == 0x85) { // 0x146085 PUYA
      static uint32_t read_buf[SPI_FLASH_SEC_SIZE / 4];
      rc = spi_flash_read(offset, read_buf, size);
      if (rc != 0) {
         ets_isr_unmask(FLASH_INT_MASK);
         return false;
      }
      for (size_t i = 0; i < size / 4; ++i) {
         read_buf[i] &= data[i];
      }
      ptr = read_buf;
   }
   rc = spi_flash_write(offset, ptr, size);
   ets_isr_unmask(FLASH_INT_MASK);
   return rc == 0;
}


Now it work fine.
Thank you.
