Can application code be put into ROM
Hi,
I would like to know if the application code can be loaded into ROM after the area where BLE stack and other necessary data is stored.
Thanks

SWITCH pin
Hi there,
We use an oscilloscope to estimate the SWITCH pin (QFN40, no.21 pin),https://imgur.com/a/COPbF
As we know, we can use this pin to know whether DA14585 is in extend sleep mode or not, right?
It is really weird that if I burn the code into SysRAM by using the booter function of SmartSnippets, the SWITCH will always high (never be low).
However, If I burn the same code into Flash, the SWITCH pin will be high only when the DA14585 is awake.
What's the reason?
Thanks you very much!
DA14585 SDK604 LE Advertising Extensions
Hi
I am working on project using DA14585 SDK6.0.4. I would like to know do SDK6.0.4 support BT5.0 feature LE Advertising extensions.
How to configure it to use and test?
Thank you

app_init not getting invoked
Hi,
I am modifying the ble_app_peripheral project. The control is not reaching the user_app_init (). While debugging through the system_init(), it was observed that the control does not go beyond the function arch_rom_init(). Please suggest the reasons for the same.
Thanks and regards

scatter file modification
Hi,
My program size is 34KB.
Then I checked retention_mode at init_retention_mode() in arch_main.c
ret_mode=get_retention_mode();
ret_mode is 0x0b , this means Sysram1/2/4 are retained.
我想小正在移动t of code in SysRam2 into empty area in Sysram4, and retain only Sysram1/4.
Please tell me how to modify scatter file.
Can I change the definition CFG_NB_PRF?
Hi there,
I find that the CFG_NB_PRF definition in da1458x_stack_config.h is 32 and it costs about 0x300 bytes in retention memory.
If I just have 2 ble profiles, can I modify it to 2?
If I modify it, Is there anything I should pay attention to?
Thanks a lot.
Where is the startup code for memory clear/copy?
Hi, I'm checking startup sequence in SDK6.0.2.
I think Reset_Handler in boot_vectors.s is the startup code.
But Reset_Handler does not have a routine of memory clear/copy (such like .bss .dat section for gcc).
在哪里做?
Aborting sleep
I have an interrupt connected to a button which I use to trigger several behaviours.
I'm finding that some of those behaviours misbehave after OTP, which I attribute to sleep mode causing me to lose data somewhere or interrupt operations such as DMA.
I'm experimenting with an alternative architecture where the interrupt sets a flag to cause these behaviours to be executed in the main loop, so I can better control the timing and order of events, but I've got a loophole I'm struggling to close.
variable in retention_mem_area0
Hi there,
I declare many variables such as following example...
static uint8_t test __attribute__((section("retention_mem_area0"), zero_init));
And my questions are...
1. After printing the address of the variable, It's 0x7FD4804(in SysRAM4:). Why?
2. Why doesn't the variable be stored in SysRAM1?
3. Does It means the variable will be cleared in extend sleep mode? But the value of the variable is still correct, why?
System Viewer File for DA14585
Hi,
I've been following your training 8 material "BLE Register" section. I couldn't find the directory you cited to locate the DA14585 systemviewer file.
