AM2634: Problem with QSPI Mode through the Lauterbach Trace32

Part Number: AM2634

Hi, Supporter

This issue is not occurred by XDS debugger. With XDS debugger application is loaded correctly and I can debug it. This issue is only occurred by Trace 32 currently.

To use QSPI mode, I did as below sequence.

1. Firstly, I set the Dev Boot mode

2. Through the SPI, I wrote the SBL and Application Image to Ext. flash. I checked FLASHFILE Dump which is correctly written or not. Used cmm file is am263x-S25FL128SA-qspi.cmm.

  • FLASHFILE Erase 0x0 ~ 0xFFFFF
  • FLASHFILE Write - with offset 0x0(BootManager), 0x40000(Bootloader), 0x80000(App)

3. Power Off and change the BOOT MODE to QSPI mode(0000)

4. Power On and attache the Trace 32 debugger and break. What I can see is that PC is in 0x39F6 continuously. What I expectation is load the Application to 0x70040000.

Could you guide or hint to how to solve this problem?

Do I need to run the initialization cmm(_am263_allcoretype_connect.cmm) before attach?
