MSP430F5172: Some question about the application of MSP430F5172

Hi Lumina,

I'm not too familiar with the requirements for the Qualcomm platform? Do you have any details you can share on it?

Regarding your schematic, I'll trust you've designed your analog side well enough for now. Do you plan to use UART BSL like mentioned in the related thread? If so you may want to add A4 and B4 for UART BSL Rx and Tx.

Hi Brandon,

We implemented the functionality on the MTK platform and now want to implement the same functionality on the Qualcomm platform. 

For CTS/RTS flow control issues, it is important that the communication between the host processor and the MSP430F5172 must be start in both directions without delay. We have realized this function by flow control in the form of RTS and CTS on MTK platform. On the MSP430F5172 side, GPIO with interrupt function is used. Interrupts must also be used in the main processor. So we want to confirm whether the Qualcomm platform is the same way.

Thanks,

Kind Regards

Hi Lumina,

From a UART perspective either method could work with this device. 

I couldn't comment on whether the Qualcomm platform is using a 2 or 4-wire implementation of UART though. I'll leave this thread open in case one of our community members is aware.

Hi Brandon,

Another question,when programming the firmware for MSP430F5172 on the android side, it will perform the following operations on B3 and D2. It has entered BSL. What is the state of MSP after execution?

static void maja_invoke_bsl(struct maja_supervision_gpios *gpios)
{
   gpio_set_value(gpios->rst, 0);
   gpio_set_value(gpios->test, 0);

   pr_info("wqw maja gpio 1");
   mdelay(100);

   gpio_set_value(gpios->test, 1);
   mdelay(10);
   gpio_set_value(gpios->test, 0);
   pr_info("wqw maja gpio 3");
   mdelay(10);
   gpio_set_value(gpios->test, 1);
   mdelay(10);
   gpio_set_value(gpios->rst, 1);
   mdelay(10);
    pr_info("wqw maja gpio 4");
   gpio_set_value(gpios->test, 0);
   mdelay(100);
}

Thanks,

Hi Brandon,

Thanks a lot. Another question, is there any suggestion to burn the code before patch? We will burn the software and then patch it for mass production.

Thanks,

Kind Regards
