## Summary arch/esp32_partition.c: There are eight possible sequence arrangements for switching the boot sequence of the three partitions (factory/ota_0/ota_1) through the ota_set_bootseq() and ota_get_bootseq() interfaces. However, it has been discovered that after executing the switch from factory to ota_1, the result read by ota_get_bootseq() is ota_0. The current solution is to directly use the target partition's number (num) as next_seq to ensure the correct increment logic of seq. Ensure the formula (seq-1) % OTA_DATA_NUM + OTA_IMG_BOOT_OTA_0 correctly maps to ota_0 or ota_1 ## Impact New Feature/Change: Issue fix (no new feature). User Impact: when exist three OTA partitions (factory/ota_0/ota_1). Build Impact:No new Kconfig options or build system changes. Hardware Impact: Only ESP32; other architectures unaffected. Security: No Compatibility: Backward-compatible; no breaking changes. ## Testing Verify the ESP32 OTA boot sequence using the relevant interfaces: ota_get_bootseq() and ota_set_bootseq().
