I would like to enable the True Random Number Generator to create advertising intervals to prevent collision among several units.
I'm editing the DA1458x_beacon_v_5.40.2 project files.
In DA1458x_config_advanced.h I define:
#define CFG_TRNG
Using Keil uVision v5.27.1.0 I click rebuild all target files. I then end up with this error:
。\ out_580 \ dialog_beacon_580.axf：错误：l6218e：未定义的符号trng_acquire（由Arch_System.O引用）。
At first the trng.h file gave me an error:错误：未知类型名称“uint8_t”
To fix this error I added this to trng.h:
#include
#include“compiler.h”//内联函数
#include "stdbool.h"
The error went away, but I still have the L6218E linker error.
Have anyone else run into this problem?
Thank you for your time.

Hi dlo,
目前不支持DA14580产品的灯塔，因为我们已亚博电竞菠菜搬入DA15585 / 56产品系列和新SDK6。请在我们的支持网站上查看DA14585 / 6：
//www.xmece.com/products/connectivity/bluetooth-low-energy/smartbond-da14585-and-da14586
有一个名为Multi-Sensor Kit的参考设计，支持信标实现。请注意，建议使用DA14585 IOT Multi传感器开发套件进行新设计。
https://www.dialog-seminile.com/produ亚博电竞菠菜cts/da14585-iot-multi-sensor-development-kit.
If you are not interested in moving into DA14585/6, please use one of the examples of SDK5.0.4 which is the attest SDK for DA14580/1/3 products.
Regarding your question for True Random Number Generator (TRNG),it is not existed as a hardware block, but we have an available API of this kind of usage, so I would highly recommended to have a look at the SDK and follow the USE_TRNG definition. You can get a 128-bit random number by calling the function trng_acquire() from trng.h/c library. To enable the True Random Number Generator you need to define the CFG_TRNG flag. A random number is generated at system initialization and used to seed the C standard library random number generator. In order to get from the 580 a random number the SDK uses the radio module and by altering the values of the radio registers it obtains the random number. Please, check the source code of trng_acquire() function.
Thanks, PM_Dialog
你好pm_dialog，
我们已经在生产环境中，因此我们无法切换到DA14585 / 6。
I am following the SDK example and enable the CFG_TRNG flag as previously posted in the original question. Following the code I could see USE_TRNG is set to 1 when CFG_TRNG is defined, however as you see in my previous comment, when I try to build. I get this linker error that doesn't seem to make any sense since I can see the include files for the trg.h and .c file included but somehow it's not able to link to the trng_acquire() function.
这是非常紧急的在这一点上,我们需要重新lease this firmware for mass production.
Ho dlo,
The L6218E linker error is typically relating to variable declarations. Could you please send me a screenshot?
Thanks, PM_DIalog

Hi dlo,
Did you have include the trng library in arch_system file? I am not able to replicate your issue. Are you using the trng_acquire in this file?
Thanks, PM_DIalog
I didn't edit the arch_system file. I do see in the file the following, which I assume has been tested and works:
#if (USE_TRNG)
#include "trng.h" // True random number generator API
#endif
在包括路径中build, I see the folder trng is included.
Hi dlo,
我打开了项目，正如您在附加快照的IMG1中看到的，TRNG，UART2和SYSTICK驱动程序未被正确包含。按照附件中找到的步骤操作，以便再次删除并添加它们。驱动程序位于DA1458X_BEACON \ v_5.40.2 \ SDK_580 \ SDK \ Platflick \ Driver文件夹路径下。之后，我能够编译项目。
Thanks, PM_Dialog
非常感谢你的帮助！
