AM2434: SBL JTAG Uniflash (Data verification fail)

Part Number: AM2434
Other Parts Discussed in Thread: UNIFLASH

Hi Experts

On my AM243x-EVM model card I can flash with SBL JTAG Uniflash example, but on my custom board

js:> loadRaw(0x80000020,0,"C:/ti/mcu_plus_sdk_am243x_08_03_00_18/tools/boot/sbl_prebuilt/am243x_evm/sbl_ospi.release.tiimage",32,false);

After entering this script, I get the error "Data verification failed at address 0x80000020 (C:\ti\ccs1110\ccs\eclipse\configuration\org.eclipse.osgi\86\0\.cp\resources\debugserver\memory.js#176).

I'll be pleased if you pay attention.

Hi Berlam Karli,

Regarding your custom board, does it have the same AM243x chip which is on am243x-evm ?

Hi Aakash Kedia,

Yes, it has the same chip with evm. Is the ddr in evm external or internal? If it is external, my custom board does not have ddr. Thinking about this, when I gave msram starting with 0x7 instead of ddr in the sbl_jtag_uniflash example's linker, I was able to write to the flash with jtag. But I can't do the same thing with uart-uniflash. I can pass the flash-writer step, but there is no progress at the offset=0x0 step and I get an xmodel send failed error. Can I write to flash with uart without DDR, if I can, how can I do it? By the way, my uart connections are correct because when I debug the uart echo example, I can see its outputs.

Best Regards,

Berlam

The DRAM is externally connected.

I would suggest the following changes in linker script to eliminate DDR from your application if you have a AM243x_ALV (the one on EVM) without an DDR memory -

Also, do you have a GP device or HS-FS device ?
