Hi TI 

There's a request that customer wants to perform on IWR6843AOP EVM.

They want to read out Radar's Firmware binnary written into SPI NOR flash by using JTAG. 

I found the link below regarding Flash Read / Write.

https://www.ti.com/lit/an/swra583/swra583.pdf?ts=1634732500320&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FIWR6843AOP%253Futm_source%253Dgoogle%2526utm_medium%253Dcpc%2526utm_campaign%253Depd-null-null-GPN_EN-cpc-pf-google-kr%2526utm_content%253DIWR6843AOP%2526ds_k%253DIWR6843AOP%2526DCM%253Dyes%2526gclid%253DEAIaIQobChMIm_KLisbY8wIVF9GWCh0q0wwSEAAYASAAEgJ-g_D_BwE%2526gclsrc%253Daw.ds

Could you please let us know how to read firmware binary of IWR6843AOP EVM using JTAG? and CCS as well? 

Thanks.

Regards, 

Jack

    Hi Jack,

    That document has the best information to add flash reads to the code. There is no easy way to read the firmware using JTAG. The only way would be to load a program via JTAG that is set to read the data into L3 memory, which can then be read by CCS. You can add the read functions into the demo_init function which should let you read the code at startup.
