esplocalizer firmware-c example missing files

[fmaurer]

Cloned esp82XX-basic example compiled and flashed to esp without issue. Everything works great.

Unable to do make all in /esplocalizer/firmware-c, compiler missing 'lib' files. What does libmain.a do and where can I get it :) ?

I read this had to do with SDK > 1.5.2, but I thought I solved this with esp-open-sdk/Makefile

#VENDOR_SDK = 2.0.0 VENDOR_SDK = 1.5.2

e.g. with SDK versions greater than 1.5.2, Espressif changed the IRAM management

I'm not sure if coping /lib and /ld was the right thing to do or is even related...

and /include. Typically I keep the whole SDK together and rename the SDKs.

Indeed that is the issue, however, Espressif made a new SDK that should work again. You can get a pre-release version of it from here https://github.com/cnlohr/swadges2017 - the file called angus_patch.

• added /include folder
• downloaded and linked prerelease SDK in esp-open-sdk/Makefile, as seen here:

# Vendor SDK version to install, see VENDOR_SDK_ZIP_* vars below
# for supported versions.
VENDOR_SDK = 2.0.0
#VENDOR_SDK = 1.5.2

#...

VENDOR_SDK_ZIP_2.0.0 = REDUCED_ESP8266_NONOS_SDK_2.0.0_20160810_with_angus_patch.zip
VENDOR_SDK_DIR_2.0.0 = REDUCED_ESP8266_NONOS_SDK_2.0.0_20160810_with_angus_patch
#VENDOR_SDK_ZIP_2.0.0 = ESP8266_NONOS_SDK_V2.0.0_16_08_10.zip
#VENDOR_SDK_DIR_2.0.0 = ESP8266_NONOS_SDK_V2.0.0_16_08_10

#the rest of the file...

• run make all
• cd to /esplocalizer/firmware-c
• make all gives same iram error

I'm not understanding where the esp82XX-basic example differs so much from the esplocalizer/firmware-c to produce this behavior. Both project's user.cfg have:

SDK = /Volumes/case-sensitive/esp-open-sdk

Just tried a make burnweb using angus SDK and esp82XX-basic produced no errors.

Could you elaborate on "keep the whole SDK together and rename the SDKs" ? Do you keep the esp-open-sdk inside of esplocalizer?

My directory structure looks like this /Volumes/case-sensitive :

• esp-open-sdk
• esp82XX-basic
• esplocalizer

[fmaurer]

Fixed it:

First was my mistake forgetting command is make burnweb while in /esplocalizer/firmware-c

However, this isn't all, it produced the following error: `Auto-detected Flash size: 32m Running Cesanta flasher stub...

A fatal error occurred: Invalid head of packet ('\xd8')`

This was fixed by commenting out the following line in /esplocalizer/firmware-c/user.cfg

#FWBURNFLAGS = -b 1000000

[cnlohr]

Which dongle do you have?

[fmaurer]

PL2303 TA based cable, using 2 level shifters for 3.3V and RX

Aah! Ok, I think that one works better at 1,500,000 baud. Dunno why.

In my infinite n00bness I have misunderstood many things, but learned much.

make burnweb and make burn accomplish different things. I was able to get burnweb to work as expected, but not make burn. This may explain why I couldn't get the fast acc CSV file to work: https://github.com/cnlohr/esplocalizer/issues/5 The esp hasn't been flashed to talk with IMU firmware code. All it has is the web GUI

It's the same iram1_0_seg error which I mistook as being fixed by using an older SDK.

My /esp-open-sdk is compiled for 1.5.1, but that still produces same error. Next I'll try cnlohr's suggestion to keep SDK together and rename multiple SDKs.
