PSoC 4100S Plus OTA firmware update over GSM

[MiM_4846431]

I am working on an application with a GSM modem interfaced to PSoC 4100S Plus through UART. I need to implement OTA firmware update over GSM interface via TCP or HTTP (depends on application). I have successfully tried UART bootloading and tested it using bootloader host application(same UART port as GSM). I am using CY8CKIT-149 (with CapSense sections broken).

The question is, how can send the same cycad file over a tcp connection or in other words, how to read the cyacd file and process it to send it over TCP -> UART -> Bootloader

Additional question - is there any way to exit bootloader after a specific time period if the data is not received, currently it seems to be in a infinite wait.

Hi,

1).The question is, how can send the same cycad file over a tcp connection or in other words, how to read the cyacd file and process it to send it over TCP -> UART -> Bootloader

>>The bootloading process happens packet by packet, you can refer to the below document page number 46.

You can also refer to the bootloader host project - https://www.cypress.com/documentation/application-notes/an60317-psoc-3-and-psoc-5lp-i2c-bootloader

2).Additional question - is there any way to exit bootloader after a specific time period if the data is not received, currently it seems to be in a infinite wait.

>>There is a timeout option in the component where you can set the wait time.

Hi Alakananda,

1. Thanks, this is helpful.

2. The timeout option seems to work only when bootloader is entered after device reset. When I enter bootloader using Bootloadable_Load() function, the device remains in an indefinite wait (I think that is expected working). Is there any option to exit bootloader in this case. If nothing works, can we use WDT?

Hi Alakananda,

Any updates on the second question?

Seems like there won't be any further responses once a question is marked as answered.

>>There is no direct option to exit the bootloader, we are checking if WDT works.
