#772 Hi,

updated the esptool, that is, i cleaned up the command parsing. Also, it is quiet by default now, to enable some info output add -v to it's commandline argument. For more info-output use -vv, -vvv, -vvvv, ... The command -d to dump a segment into a file is deprecated noe, use -es instead. It still recognizes -d, but emits a warning then.

Also modified the Makefile for compiling apps, it now shows "FW ...." when calling esptool to create the firmware images, and also to change the -d into -ds for esptool dumping the irom0 segment.

NOTE: The Makefile uses "esptool" as name for the binary to call. Make sure you don't have a directory called "esptool" where you store the "esptool.exe" binary, it will confuse the make process and cause an error.

Attached are the updated files.

esptool-0.0.2.zip

Makefile_AT_0.9.1.zip

Makefile_IOT_0.9.1.zip

#959 I got sick of waiting for GCC :-/ and got moving with the stuff I've found on the forums here, and I'm getting the following error; Any idea what could cause it?

It looks like you are missing the user_main.c in the compile process, since that is the file which contains the user_init() function. Did you move areound the files correctly to the new directory structure suitable for the new makefile?
