JTAG SWDIO SWCLK access after PLT programming

Thu, 2019-08-15 06:22--dlo

I have a few units that has gone through production and have had their OTP memory programmed. No flash on board. In the configuration XML I have specified enable JTAG, but when I'm trying to reprogram the RAM of a unit via JTAG, I am not getting any communications on SmartSnippets Toolbox... is my understanding of JTAG enable in the configuration wrong?

Thank you,

otp拷贝的时间和外部spi flash拷贝的时间大概是多少?

Thu, 2019-08-15 04:24--cgha

我现在是通过外部Mcu跟da14580通信,发现flash启动就能正常,但是换成otp启动后通信io口和flash启动不太一样,问一下他们启动时拷贝的时间分别是多少,哪个文档有讲这个? 按道理来说otp拷贝肯定更快。

DA7280 external force sensor I2C interface

Mon, 2019-08-12 23:41--anton002

Is there a way to interface SingleTact FSR I2C com with DA7280 eval board?

Single Tact spec

  • Supply Voltage, Vcc 3.7 – 12V
  • I 2C clock frequency 100KHz or 400KHz
  • I 2C bus level 3 – 5V
  • I 2C output range (sensor data) 10-bit (Operational FSR output 9-bit)
  • Analog output range 0 – 2V (Operational FSR output 0.5 – 1.5V)
  • Permitted analog output load >5K
  • Frame Sync level 3.3V C
  • MOS output Sensor update rate (I2C or analog) >140Hz (dependent on settings)

Switching between iBeacon and Eddystone advertising

Mon, 2019-08-12 15:28--dlo

I am using the beacon demo code DA1458x_beacon_v_5.40.2_0 and would like to do the following:

Wakeup -> advertise iBeacon ->stop adv-> advertise Eddystone ->sleep->repeat

Where would be the most logical place to insert my code without breaking other functions?

Can I leave the: #define DEFAULT_BEACON_TYPE IBEACON

and then after the iBeacon advertisement, stop the advertisement, initialize the data for Eddystone, then restart advertisement?

Are there any example I can look for to do such a thing?

Thanks!

DA14580用SmartSnippets烧录spiFlash不稳定问题

Sun, 2019-08-11 12:23--shezhe9

大家好我在用da14580在做一颗产品,现在试制了三块板卡,发现SPI Flash的烧录不稳定。会出现erase不稳定,烧录也不稳定情况。现在汇总情况如下:
烧录环境 SmartSnippets
烧录接口 JLINK烧录(不稳定的板卡尝试UART烧录情况类似)

SPI FLash型号 W25X20CLSNIG

硬件链接:Port0 pin-0345
板卡1:烧录30k的code比较稳定基本每次都能成功擦除 成功烧录

烧录120K的code非常不稳定,10次过程中erase只能成功2-3次,burn的时候有6个block,几次只能烧录第1.2.3个block 后面block烧录失败。只成功了一次全部成功烧录

板卡2:烧录30k的code不太稳定基本10次有5次能成功擦除 成功烧录

烧录120K的code及其不稳定,10次过程中erase只能成功2-3次,burn的时候有6个block,几次只能烧录第1.2.3个block 后面block烧录失败。一次都没有完全烧录成功。
