* icetime: avoid string + int Clang warningEd Maste2020-05-281-1/+1
| | | | | | Clang warns that "adding 'int' to a string does not append to the string". Although a false positive it's trivially avoided by using the array index equivalent &PREFIX[1].

| * | icepack: Fix Windows-only stack overflow in CRAM pbm generation (fixes #241)The6P4C2019-12-081-1/+19
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Windows, attempting to generate a netpbm image of the CRAM with `icepack -b` causes the tool to crash after writing only the netpbm header due to a stack overflow. The bug did not appear on Linux. This was traced to a large stack-allocated variable length array (`tile_type`) inside `FpgaConfig::write_cram_pbm`. For an 8k ice40 with 4 banks, `cram_width = 872` and `cram_height = 272` the `tile_type` array ends up at `4 * 872 * 272 * sizeof(uint32_t) =` 3794944 bytes, or about 3.6 MiB. The fix replaces the large stack VLA with an array of 4 (bank) 2D C++ vectors, moving the large amount of data to the heap. Even though the fix is not in a Windows-specific code path (and hence applies to all platforms), I think it's wise to eliminate such a large stack allocation entirely. The fix has been tested working on both Windows and an Ubuntu WSL install.

| |/ | | | | | | | | | | | | | | | | This patch adds support for icepll to try multiple input frequencies to find the best crystal for the desired output frequency. The values tested comes either from a specified file using-B, or from a default set of frequencies from Mousers "normally stocked" crystal oscillators.

| | | | | | | | | | | | | | | | | | | | | | If the flash was in a 'weird' mode (like CRM, QPI, ...), sending a continuous stream of 0xff should take it out of it. It looks like the previous code was trying to do that, but was only transferring 8 bits and then 2 bits which is way too short. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
