René van Dorst bbd4656810 SERIAL: Use Timer1 instead of Timer2 
Use Timer1 as baudrate generator.
Timer1 can be programmed to have the same accuracy and deviation as
Timer2, up to 115200 at F_SYS = 125 Mhz. See comment
setup_serial_timer1() comment for valid baudrates and settings.
Timer1 is used in 8-bit auto-reload mode.

Timer2 16-bit auto-reload can now be used for other tasks like SYS_TICK.

René van Dorst 8b061d5fb9 SYS_TICK: Use Timer2 instead of Timer0. 
Downside of Timer0 is, we have to manually reload
the timer value. Timer2 can do that automaticly.
This saves a lot of time in the interrupt-handler
of the Timer.

Currently Timer2 is used for baudrate-generation
but in a separete commit this is moved to Timer1.

René van Dorst 9ff114d234 SYSTICK: Fix writing value to TMR0 registers. 
A `%` modulo operator was used instead of a
`&` and-operator, to split a 16 bit value into two
8 bit values.
This causes that the SYSTICKs were 0.1% too fast.

Replace the manual split with a sfr16 type, so the
compiler does the split for us.

René van Dorst 0abe83e3e5 sfr: add 16 bit SFR for the timer0. 
So we don't have to manual split 16-bit value into
for bytes.
Let the compiler do the work.

René van Dorst 2a7b8f9838 Merge pull request #59 from logicog/timer_fixes 
Fix internal timer tick counter for housekeeping.
Because of the high F_CPU and low SYS_TICK.
Timer0 can easy overflow.
Now this is known and fixed.

Put all the device information in one struct `machine`.
So all the device information is defined in one place.
Also easier to add new devices.
Show device name also on website.
Fix SFP status information, some devices have a different SFP layout.
Reworks GPIO handling
Able to set manual port speed, duplex for the RJ45 ports.

René van Dorst f59be9cf2b Added software version + git short hash string to firmware. 
The Makefile has the version number and generates a version.h which
has VERSION_SW define that looks like "v<VERSION>-g<GIT_SHORT_HASH>".

Software version shows at boot in the serial console.
And shown with command: `version`.

It can also be requested via `information.json`.
```

    "ip_address": "192.168.10.247",
    "ip_gateway": "192.168.10.1",

René van Dorst 7d94f3d328 Improve JSON response. 
Remove all the extra spaces from the json.
Also simplify the generation of the json.
Codespace is cheap so duplicated strings is not an issue.
But generating strings from different parts is more expensive in clock cycles.

Add a helper funcion `bool_to_html()` to generate bool value for html output.

René van Dorst e5ee4594ef installer: fix left over typo SFR_FLASH_DUMMYCICLES 2025-10-09 20:03:08 +02:00
René van Dorst 928cf1cf58 http: upload: make sure we don't cross flash page boundaries. 
This causes the address pointer to wrap back to the front of the page.
Which results in that the beginnen of the page can have data for the next page.

René van Dorst a59f92a648 Also use struct flash_region in flash_read_security(), flash_sector_erase(). 2025-10-05 16:53:46 +02:00
René van Dorst 52fa41760c Don't pass the first 16-bit argument via xdata. 
Calling confention already uses the DPTR registers as the first two byte arguments.
So adds a lot of code to put the 16-bit value on xdata, still passes the 16-bit xdata ptr in DPTR registers, then read the xdata value.
So it doesn't save any sram bytes.

René van Dorst 884bc18a61 Remove flash_read_bulk(), refactor website and execute_config(). 
flash_read_bulk() is kind of a printf function. But did not work as well.
flash_read_bulk() was used in the http generation so this needed to be changed as well.

For the website we decided that we are going to use CSR(Client Side Rendering).
So every HTML and JS files are now static.
Variables are fetched via json calls and output is render on the client side.
Also usefull for the future when we want a REST like API.

execute_config() was also using flash_read_bulk().
This have been replaced with flash_read_bulk() and parsing the flash_buf buffer.

Replaced in the function which contains `8224` in the name the
`phy_write(0x00, ...)` with `phy_write(RTL8224_PHY_ID, ...)`, same for the
`phy_read(0x00, ...)` with `phy_read(RTL8224_PHY_ID, ...)`.

René van Dorst b8928a8bcd Replace manual SFR_DATA_0 and SFR_DATA_8 pair read and write with SFR_DATA_U16. 
Also added SFR_SMI_REG_U16.

Doing pval = reg_h; pval <<= 8; pval |= reg_l; dont always optimized by the compiler a some places, not all.

A snipped of the diff between two .asm files.

René van Dorst 9dafeab490 Added SFR_NIC_DATA_U16LE and SFR_NIC_RING_U16LE. 
Let's use sfr16 for NIC data and ring.
SFR define can so reordered to it does the BE to LE swap for us.

René van Dorst af0135bcce Add sfr16 SFR_REG_ADDR_U16. 
So instead do it manual split a uint16_t in to two uint8_t.
The compiler can do it, so reduces user error.
Note: compiler writes the lower/LSB part first.
      When that is importent this can´t be used.

Assembly is still the same except note above.

René van Dorst 7ff028303d Add phy_write() with bit_mask lookup inside the function. 
Move the lookup saves a lot of instructions for every phy_write() call.

Assembly diff for one change.

Replace all phy_write_mask(bit_mask[<var>], ...) to phy phy_write(<var>, ...).

René van Dorst d6ea9be4c0 rename phy_write() to phy_write_mask(). 
It seems that bit_mask[phy] lookup is expensive and it used in many places.
But most of the time we only addressing a single phy.

René van Dorst 3d80f73383 fix: comp. warning 283: function declarator with no prototype. 2025-08-30 22:51:19 +02:00
René van Dorst e859769e5c http: use python3. 
Fix compile issue where system don't have python2.
I get error below.

/bin/sh: line 1: ./treatasm.py: cannot execute: required file not found
make[1]: *** [Makefile:15: httpd.rel] Error 127

Debian has python3 a long time so use it.
See https://wiki.debian.org/Python
