Example 1: in our project, internal flash - 8MB - esp32-s3-Fn8 external flash - 16MB - Winbond. During every startup around 32kb of content need to copy from external flash to internal flash(so, here need to allocate 32kb memory in internal flash with fixed location) Example 2: We need calculate che...

Hello Team,
How can i add variable(flag) in fixed location of ROM and RAM. Any sample for customized linker and CMake files

Our hardware: eSP32-S3-FN8

In Customized bootloader, The below test code esp_err_t err = esp_rom_spiflash_erase_block(0x13); if(ESP_ROM_SPIFLASH_RESULT_OK == err) { ESP_LOGI(TAG, "flash erase successfull"); } { ESP_LOGI(TAG, "flash erase not not successfull"); } err = esp_rom_spiflash_write(0x130000, data, strlen(data)); Why ...

Hi Team,
During Application and bootloader binary file generation, unused part of allocation need to fill with pre-fill values(0xFF or 0x00).
Example: Application ROM allocated 1MB, but really used 512KB then remaining 512KB need to fill with pre-fill values.

Hi Team, In my project, Application start with 0x30000 with 1MB size Backup application start with 0x130000 with 1MB. Here, During my Implementation, I try to erase 13th block start of backup application, Once I triggered this erase command from bootloader after system continues reset. Even chip ful...

Hi Team,

We need to access external flash in customized bootloader(read/write/Init) through SPI 2 interfaces.

Chip: Esp32-S3-FN8
External Flash: WINBOND 16MB
