This commit changes only ones with the default 2048 and leaves the others. E.g. this leaves SYSTEM_RAMTEST_STACKSIZE, whose default is 1024. I guess those need to be inspected one-by-one.

order to throttle the rates of data transfer to fit within the

|

The size of one buffer used to read data from the remote peer. The
|
|
total buffering capability is SYSTEM_ZMODEM_RCVBUFSIZE plus the size
|
|
of the RX buffer in the device driver. If you are using a serial
|
|
driver with, say, USART0. That that buffering capability includes
|
|
USART0_RXBUFFERSIZE. This total buffering capability must be
|
|
significantly larger than SYSTEM_ZMODEM_PKTBUFSIZE (larger due
|
|
streaming race conditions, data expansion due to escaping, and
|
|
possible protocol overhead).

Read multiple bytes of file at once and store into a temporal buffer

Local sender can sample reverse channel while sending. This means

in particular, that Zmodem can detect if data is received from the
|
|
remote receiver while streaming a file to the remote receiver.
|
|
Support for such asychronous incoming data notification is needed to
|
|
support interruption of the file transfer by the remote receiver.

This capapability is not yet supported. There are only incomplete

hooks in the code now! Enable only if you want to see the warning.

Some MMC/SD drivers may fail if large transfers are attempted.
|

As a bug workaround, you can set the maximum write size with

|
this configuration. The default value of 0 means no write limit.

Enable Zmodem debug output. This debug is unrelated to the internal
|
|
NuttX debug option; it does not use the SYSLOG channel but, instead,
|
|
outputs debug information on stderr. Obviously, enabling this
|
|
option will likely cause you all kinds of problems if you intend to

use /dev/console to transfer files!
