Hi
Please refer the forum link asking question is continuation of this,
SDK Using for FW upgrade : ti154stack_linux_x64_4_40_00_03
example code using : cc13xx-sbl
OD Platform : Linux Ubuntu
Interface : UART
Chipset : CC2652R7
Host to upgrade the FW : Linux platform processor
Client to download the FW : CC2652R7 chipset
On MCU side We are using DIO2 as Rx and DIO3 as Tx. HW connection was proper. When we are trying to upload a FW from Linux processor to MCU we are receiving a NACK for Erase itself as shown in below image,
As shown in the image we are always receiving 51(Hex : 0x33) for erasing itself. Not even once we are able to upgrade it
What might be the reason for this ? Please explain here
