Hello,
I am hitting an issue with OpenOCD and Segger JLink when trying to
program a Kinetis MCU (MK22FX512VLH12). Until Commit 2caa3455ad
everything is fine, starting with Commit 7f260f5009 and up to latest
master d8ac0086f9 initial flashing without using the device's memory map
fails. The error message indicates that increasing the timeout limit
might help. Executing a "set remotetimeout unlimited" does not change
anything about the issue and the message displayed though.
# OpenOCD
```
$ openocd -f interface/jlink.cfg -f myboard.cfg -c 'gdb_memory_map disable'
[...]
** Programming Started **
Warn : keep_alive() was not invoked in the 1000ms timelimit. GDB alive
packet not sent! (1524). Workaround: increase "set remotetimeout" in GDB
** Programming Finished **
[...]
```
Complete output is attached as openocd.log.
In constrast what this part looks like when it is working (e.g. on
2caa3455ad):
```
** Programming Started **
auto erase enabled
wrote 61440 bytes from file myprog.hex in 1.517295s (39.544 KiB/s)
** Programming Finished **
```
# GDB
```
$ arm-none-eabi-gdb -ex 'set confirm off' -ex 'target remote
localhost:3337' -ex 'mon kinetis mdm halt' -ex 'mon reset init' -ex 'mon
program myprog.hex' -ex 'quit'
```
Complete output is attached as gdb.log.
# Board config
```
transport select jtag
gdb_port 3337
set CHIPNAME egs-z-supervisor
source [find target/kx.cfg]
set CHIPNAME egs-z-active
source [find target/kx.cfg]
$_TARGETNAME configure -event reset-init {
puts "-event reset-init occured"
}
```
I'd be grateful for any help.
Regards,
Jonatan H. Zeidler
