Compile bare metal code that uses push and pop instructions (stack). +2. Run QEMU with bare metal code. +3. Connect via Lauterbach Trace32 and check the displayed SP register value. +Additional information: +![T32_badA76_SP_reg_display](/uploads/e6af1ac3e32072274089e6dc0cdf0266/T32_badA76_SP_reg_display.png) +This is a screenshot from QEMU 8.0.0, but updating to QEMU 8.2.0 does not resolve the problem. + +I have discussed this with Lauterbach Trace32 support with these results: +- Trace32 uses RSP protocol `p` packets to read some registers, including SP_EL1. GDB seems to use `g` packet. +- QEMU responds to `p` packet with an invalid value, which causes Trace32 to display invalid value. + +Some related RSP protocol logs from Trace32. +![T32_sp_1](/uploads/cbe34d19d3ede30549e6c4d781bb6630/T32_sp_1.png) +![T32_sp_2](/uploads/73e22dbf83ec00b939077dfeb7bfa208/T32_sp_2.png) + +Different part of RSP protocol log: +``` +Sending packet: $p20#d2 ... +receiving packet: ec00004000000000 +``` +So it looks like Trace32 can receive different values that zero as response to `p` packet. -- cgit v1.2.3
