MSP432P401R: "Information Memory" partition missing

Michal Koutny

Part Number: MSP432P401R
Other Parts Discussed in Thread: SEGGER

Hello,

I bough several MSP432P401RIPZR from mouser.com and placed to my custom PCB.

When I try flash it via J-Link or XDS110, SWD interface, operation crash on command "g_DeviceID = __readMemory32(0x0020100C, "Memory");".

I can read chip memory via segger JMem.exe, but "Information Memory" partition on adress 0x0020000 to 0x00203FFF is missing, it is like hardware part of memory is missing, rest of memory I can read without problems. Same behavior shows via XDS110 and IAR debug. All chips I bough have same behavior.

What do you thing? Are chips broken or I missed some crucial step in flash process? What can I try next?

Best regards

Michal

First, let's start with the physical connection, Vcc, GND, Reset, and JTAG. Do you have any pullups/downs on the Reset or JTAG lines?

The device ID and device descriptor table are found in the datasheet. At address 0x0020100C should be 0x0000A000 for the device MSP432P401RIPZ. What is the die revision marking on the chip? B, C, or D?

Regards,
Chris
