When generating an Application that runs in PSRAM, some initialization procedure did not execute.
I found out that e.s. for the Uart the UART_t declaration does not have the const prefix. Therefore the structure is allocated in the .bss section and not
as it should be in .rodata. After boot (not initialized) !!. The pointers declared inside point to nowhere and the
program crashes. The Problem maybe is not linked to the missing const prefix, becaus running from flash the values
ar initialized and correct. Maybe it is linked to the linkedscript.
I took the linkerscript from the ASC Loader example, but it seems that the init values of the variables etc are not
present in the "PSRAM_1" image. As in the flash linkedscript for the data segments

.data { ...} > SRAM_combined AT > FLASH_1_uncached

i added/modified to

.data {....} >SRAM_combined AT > PSRAM_1

Someone has any suggestion ? It is correct what i have done ?



In the output file generator was missing the .rodata section (-j .rodata). Show Less

Hello.. I'm using XMC4800 EtherCAT relax kit. I tried to debug in GDB Segger Jlink debugging but I got following errors.
JLinkGDBServerCL.exe
arm-none-eabi-gdb
semihosting and SWU
In console I got "Segger J-link GDB server v6.00d terminal output channel closed by the GDb server". So I couldn't debug in that mode.
But when I debugged in GDB microE debugging it worked fine. But I want to use GDB Segger J link debugging because in every documents related to XMC they have used the same. Please help
me to solve this issue. Show Less

I am working on fairly large project with an XMC4700. It has a lot of APPS set up for ADC, UART, USB, CAN, I2C, PWM, DIGITAL_IO, PIN_INTERRUPTS, etc.. I want to add another PIN INTERRUPT app and I get an error message that DAVE is not able to grant my last hardware resources request. I am fairly confident I have some pins capable of this feature left (or maybe there is a conflict I don't know of) so I am lost as to best figure this out.

The DAVE .log file shows:

There is a lot more after this and if it is pertinent, please let me know and I can post it.

It would be great if someone could give any pointers on how to address this.

Thanks in advance,

Hello,

Apologies if this has been asked before - I searched & couldn't find anything.

How do I get Dave to remember / reload my open files? Right now I have a bunch of files open. I close Dave. I open Dave. And Dave starts up "blank" - I need to reload my files again. I've been trying all kinds of settings in the preferences menus with no luck.

Other Eclipse-based programs I use (eg Code Composer Studio from TI) don't have this problem; they start up with the same settings (files open etc) as when they were shut down. But I don't seem to be able to get Dave to remember this. I see this behavior on 2 different PCs.

Any tips would be appreciated. Thanks. Show Less

Hi,

I have a problem with a piece of code written in startup_XMC4400.S:
I need to jump to an external init function with a well know address before jump in main, so:
+ ldr r0, =0x0C020200
+ blx r0

ldr r0, =main
blx r0

When I debug step by step (step into) that works but if I press continue to run this code, it fails (VAC0_G3_3_IRQ_Handler crash).

I don't understand why this work step by step and crash in free running.

How can i do to investigate/solve this problem? Show Less

Hi.

I am unable to connect the output ST of a CCU4_SLICE_CONFIG_x to "event_in0" input of another CCU4 SLICE_CONFIG_y.
I am using the HW Signal Connectios window, selcting CCU4_SLICE_CONFIG_x--> source Signal (ST),
connect to --> CCU4_SLICE_CONFIG_y, but in the Target Signal menu, it only appers in0, in1 and in2. However I expected to see in the
Target Signal menu, the "event_in0" that I create in the CCU4_SLICE_CONFIG_y and that already I can see in the HW Signal Connectivity.

Can anyone tell where is my mistake?
I would like to connect CCU4_SLICE_CONFIG_x-->ST, to CCU4_SLICE_CONFIG_y-->event_in0 to Start the timing of CCU4_SLICE_CONFIG_y.

Best regards.
Carlos. Show Less

Hi,

I'm new to DAVE and need help with debugging my XMC4800 Relay Kit.
When I create a new "DAVE CE" or "Simple Main" project I'm not able to use the debugger. The code download works fine but then the debugger terminates with "no source available for 0x0".
When I use the "Easy Start" Project the Debugger works fine.
Which Checkbox do I have forgotten? Maybe there is also a tutorial which explains this but I haven't found it.

Thanks. Show Less

Hi all, is it possible to download older releases of DAVE4?

I really need to import the example project called Encoder_FOC_Motor_Example2, but it doesn't work in the latest DAVE, nor in the 4.3.2 version.
Thanks in advance Show Less
