From 3036a1f4cc41aaf4d6c1501c873a9dbd451bd9d2 Mon Sep 17 00:00:00 2001 From: Florian Beier Date: Fri, 13 Apr 2018 14:45:50 +0200 Subject: [PATCH] Add note on flash mode Some modules require the flash mode to be `dio`, otherwise the module won't boot. I didn't know that at first and was wondering why my new ESP-12F module wouldn't boot. Maybe that is one reason why people are reporting none booting modules recently? --- FLASHING.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/FLASHING.md b/FLASHING.md index c8d3c7e..318308e 100644 --- a/FLASHING.md +++ b/FLASHING.md @@ -83,7 +83,7 @@ esptool.py --port /dev/ttyUSB0 --baud 230400 write_flash -fs 32m -ff 80m \ 0x00000 boot_v1.5.bin 0x1000 user1.bin \ 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.bin ``` -I use a high baud rate as shown above because I'm impatient, but that's not required. +I use a high baud rate as shown above because I'm impatient, but that's not required.
