[ESP32S3] Incomprehensible offset if "CONFIG_ESP32S3_USE_FIXED_STATIC_RAM_SIZE" is used (IDFGH-8850)

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

Hi,
if the KConfig option "CONFIG_ESP32S3_USE_FIXED_STATIC_RAM_SIZE" is used later in the memory.ld file the following lines can be found:

esp-idf/components/esp_system/ld/esp32s3/memory.ld.in

Lines 120 to 125 in 439a709

	#if CONFIG_ESP32S3_USE_FIXED_STATIC_RAM_SIZE
	/* static data ends at defined address */
	_static_data_end = 0x3FCA0000 + DRAM0_0_SEG_LEN;
	#else
	_static_data_end = _bss_end;
	#endif // CONFIG_ESP32S3_USE_FIXED_STATIC_RAM_SIZE

The used offset 0x3FCA0000 is incomprehensible. This not the beginning of any memory region of the ESP32S3. Could you please explain the used address? If not this seems to be a bug.

This may also related to the issue #10270. At least it can be analyzed of fixed together.

Thanks for reporting.

Yeah, I think you are right. Seems like we have done a poor job of updating this option for new chips.

Thanks for reporting it, we'll take a look.
