Customized Setup Of Toolchain - Espressif ESP32-S2 Programming Manual

Chapter 1. Get Started
• tag3:N in the rule "tag1:I tag2:W tag3:N *:V" is more meaningful because without tag3:N the
tag3 messages could have been printed; the errors for tag1 and tag2 will be printed at the specified (or
lower) verbosity level and everything else will be printed by default.
A More Complex Filtering Example
load:0x40078000,len:13564
entry 0x40078d4c
E (31) esp_image: image at 0x30000 has invalid magic byte
W (31) esp_image: image at 0x30000 has invalid SPI mode 255
E (39) boot: Factory app partition is not bootable
I (568) cpu_start: Pro cpu up.
I (569) heap_init: Initializing. RAM available for dynamic allocation:
I (603) cpu_start: Pro cpu start user code
D (309) light_driver: [light_init, 74]:status: 1, mode: 2
D (318) vfs: esp_vfs_register_fd_range is successful for range <54; 64) and VFS

I (328) wifi: wifi driver task: 3ffdbf84, prio:23, stack:4096, core=0
The captured output for the filtering options PRINT_FILTER="wifi esp_image:E light_driver:I"
is given below:
E (31) esp_image: image at 0x30000 has invalid magic byte
I (328) wifi: wifi driver task: 3ffdbf84, prio:23, stack:4096, core=0
The options ``PRINT_FILTER="light_driver:D esp_image:N boot:N cpu_start:N
vfs:N wifi:N *:V" show the following output:
load:0x40078000,len:13564
entry 0x40078d4c
I (569) heap_init: Initializing. RAM available for dynamic allocation:
D (309) light_driver: [light_init, 74]:status: 1, mode: 2
Known Issues with IDF Monitor
Issues Observed on Windows
• Arrow keys, as well as some other keys, do not work in GDB due to Windows Console limitations.
• Occasionally, when"idf.py" or"make" exits, it might stall for up to 30 seconds before IDF Monitor resumes.
• When "gdb"is run, it might stall for a short time before it begins communicating with the GDBStub.

1.16.5 Customized Setup of Toolchain

Instead of downloading binary toolchain from Espressif website (see
toolchain yourself.
If you can't think of a reason why you need to build it yourself, then probably it's better to stick with the binary
version. However, here are some of the reasons why you might want to compile it from source:
• if you want to customize toolchain build configuration
• if you want to use a different GCC version (such as 4.8.5)
• if you want to hack gcc or newlib or libstdc++
• if you are curious and/or have time to spare
• if you don't trust binaries downloaded from the Internet
In any case, here are the instructions to compile the toolchain yourself.
