LWIP "Generate Code" error

[#1]

hi,

after upgrade to DAVE 4.2.2 and install LWIP, i get an "Generate Code" error : in "File "ethernetif.tcmp"

"Cannot invoke method toInteger() on null object ethernetifc.tmpl /LWIP_TEST/Dave/Model/APPS/ETH_LWIP/v4_0_4/Templates line 498 Groovy Template"

out.print("""
port_control.clk_rmii = (XMC_ETH_MAC_PORT_CTRL_CLK_RMII_t)${eth_lwip_inst.hwres_eth_mac.getRegValue("con","con_rmii").toInteger()}U;

attached is the (XMC4700) DAVE CE Project.

Hi everybody,

I've noticed the same issue but only when I try to generate the code for a XMC4800. For XMC4500 the code Generation works.

Hi Niclas, Torsten,

I had the same problem initially. It seems that the device description was not installed properly in the previous update.
After I reinstalled the device description, it managed to work for me.

Here are the steps I did, can you try please:
#1) Select "Help -> Install DAVE APP/ Example/Device Library ..."
#2) In the Library Manager Wizard, select "Work with: DAVE APPs Library Manager"
#3) Uncheck the Filters "Hide items that are already downloaded", select "Library_DAVEDeviceDescription -> Dec_Release_2015_12_15". This will install the device description files for the product again.
#4) Create a new DAVE CE project and add the ETH_LWIP APP.

Hi Niclas!

Great! 🙂

Hi Daryl,


thank you, it works.

But is there a way to reinstall the devicedescriptiors for an existing (large) Project ?

...I found the answer myself: Make an "APP's Upgrade" to the project.

Hi Torsten,

Yes, you are absolutely right, it is possible to do a "DAVE Project Upgrade -> APPs Upgrade".
This can work if the project contains older versions of APP. During the upgrade to the latest available APP version, it will also update the latest files to the project.
