Jlink read for new NRF52833 REV3 xxAA board

[zwyydls]

Hi~ I have a new NRF52833REV3 xxAA board, and I need to read its SRAM. However, when I use the JLink command to read it, I get 524288 bits 0. I have tried recover and erase, and still get 0. What should I need to do to obtain a normal bin file?

Sorry, it‘s NRF52832 REV3 xxAA board.

Hello,

Have you tried to use programmer app https://infocenter.nordicsemi.com/topic/ug_nc_programmer/UG/nrf_connect_programmer/ncp_introduction.html?cp=10_3_1) of nRF Connect SDk to program the chip? 

Which command you use to read the RAM? Here is a list of commands (https://infocenter.nordicsemi.com/topic/ug_nrf_cltools/UG/cltools/nrf_nrfjprogexe_reference.html?cp=10_1_3_0) programming SOC from nrjprog. For reading data from RAM, you can try the following command.

Thanks.

Best Regards,

Hi~I didn't program the chip. And  I used JLink  savebin ./TEST_0.bin 0x20000000 0x10000  to save the  data from RAM. 

Thanks.
