RX/TX Flashing wiring for ESP32 Wrover Chip

Difference between make build and make all

What is the difference between make build and make all?

ESP-IDF Programming Guide wrote:Compiling your project

make all

… will compile app, bootloader and generate a partition table based on the config.
But is make build not also doing the same?

Weird, it's working there (esp idf versions are the same): Here's the test menu, pick your combo: (1) "can probe SD" [sd][ignore] (2) "can probe SD (using SPI)" [sdspi][ignore] (3) "can write and read back blocks" [sd][ignore] (4) "can write and read back blocks...
