Unable to flash s132 on nRF52832

[AmitChauhan]

I am using TAIYO-YUDEN EYSHCN, which is having Nordic-nRF52832 chip on it. As per document from TAIYO-YUDEN, recommended to flash s132-firmware on it. I downloaded s132_nrf52_3.1.0_softdevice.hex(size-342kb) from nordic site and flashing it using nRF-go studio on region-0, but after flashing it showing only 128kb on region-0.

I'm not sure its possible to update the SD again if you've overwritten it with a non-bootloader version.

As far as I could tell by reading the product spec, it looked like the board just has a USB to Serial converter on it, not an SWD interface See www.yuden.co.jp/.../TY_BLE_EYSHCN__EVBManual_V1_0_20160317.pdf

page 2

"Serial UART interface and power supply are possible with one USB cable."

In which case, if you replaced the SD + Serial bootloader with just an SD, there would be no bootloader to upload anything else via the USB to serial connector.

The manual also states

"And this board has the SWD connector terminal for software development."

Which means you will need to connect an external SWD programmer e.g. JLink or one of the many other SWD programmers that are available, in order to upload anything else onto the board

BTW. Unless you actually want to develop with the module on that board, I don't really see why anyone would buy it. The cost is very high for a module + USB to Serial chip.

You would be better off buying a development kit from Nordic, as the price is almost the same but the Nordic DK's come with a JLink compatible SWD programmer

SoftDevice S132 v.2 is compatible with SDK 11. See this compatibility matrix for more details.
