i.MX6ULL internal Flash jtag programming

karsten — Thu, 31 Jan 2019 13:23:36 GMT

Hi,

at the moment I am starting with the i.MX6ULL at a custom board.

I use the document "Getting Started with MCUXpresso SDK for i.MX 6ULL Derivatives " to nice start.

Until now I was able to download and debug (Segger Base Debug Probe) the "Hello World" example from SDK_2.2_MCIM6ULL .

I downloaded in the DDR and it works.

Now I would like to download and debug in the flash memory. Is this possible with an internal flash-memory of the i.MX6 or is it necessary to have an external flash-memory ?

In the memory map is a QSPI1 Memory, is this only for external connection or is this a real internal flash which i can use to program.

Moreover I have an external NAND Flash. Is it possible to program this via Jtag and use it for my application ?

Best regards

Karsten

Hi Karsten

for programming images to flash MFG Tool is used, this is described in

sect.5 Run a demo using Manufacturing Tool (MFGTool)

Getting Started with MCUXpresso SDK for i.MX 6ULL Derivatives

For nand one can look at

How-To use NAND boot on i.MX6UL EVK board

Unfortunately I am not aware of options for programming flashes using jtag.

i.MX6ULL has not internal flash-memory.

Best regards
igor
