Hi

I'm testing with the ESP-01 module.
I'm following the instruction find at: https://tttapa.github.io/ (A-Beginner's-Guide-to-the-ESP8266)
All ok until "Uploading files to SPIFFS"

The problem is that I can't read the file uploaded with a browser.

Trying to isolate the problem I write this code where I do:
- Format the SPIFFS
- Show info about SPIFFS
- Open in write mode the file test.html
- Write 4 bytes
- Close
- Show again info about SPIFFS

Until here all seems to be ok, but when I try to open the file I receive the error -10002 (SPIFFS_ERR_NOT_FOUND)

In a more complex sketch I receive also the error -10012 (SPIFFS_ERR_IS_FREE) and when I try to write a second time the
file test.html it disappears from the directory.

Someone can help me?
Thank you
Livio

Problem solved.
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 follow the instruction and I change the file ESP.cpp, replacing the function EspClass::flashWrite with:

Code: Select all

bool 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.
